Bad Taste.
I ordered all 6 tubes and tried all tastes.
Energy Wise its good. I got 1 portion for 3.5 sek. Which is also pretty good but the taste is just not there. It tastes bad , like medicine. And there are other energy drinks in the market that you can buy for 3.5 sek per portion which do actually have good taste. So if these were a bit cheaper. Perhaps it would be worth for ignoring the taste.

Hi Hisko!
Thank you for taking the time to try all six flavours and for sharing such detailed feedback. We’re glad to hear the energy effect works well for you, and we understand that taste matters just as much.
Your point about price compared to other energy drinks is a fair one, and we’ll pass your comments on to the team.

Best energy drink ever
I only tried apple flavour for now, but this is already the best energy drink I've ever tried.

Hi Jure!
Thank you so much for your kind words! We’re thrilled to hear that the Apple flavour has already become your favourite energy drink. We hope the other flavours impress you just as much when you try them.

It's really great
While the taste isn't anything to write home about the tablets are still flavorful enough to get enjoyment out of. What i'm more impressed by is the quality and price of the product. An energy drink for 40 cents is insane for this age. The shipping was fast, the website is clear about what you're getting and you do have to commend Fuse for not using A.I in the marketing. Overall FUSE is great.

Very disappointing experience
Ordered on September 25 with 2–4 business day delivery. The package never arrived, and customer support repeatedly told me to contact the carrier instead of handling the issue themselves. I eventually received a refund, but never the product. Poor shipping management and customer service.

Hi Edoardo!
Thank you for taking the time to share your experience, and we’re sorry your order never arrived. A delivery that doesn’t show up within the promised timeframe is frustrating, and it’s not the standard we want to deliver.
We also understand that being sent back and forth between us and the carrier was not the help you expected. We’re glad the refund went through, and we’ll pass your feedback on to the team so we can improve how we handle delivery issues.

Didn’t like the taste
I ordered one tube to try out, and if i liked it i would get more. The shipping was fast, the package is nice, and the process is easy. But i gotta say i was kind of disappointed by the taste. I even tried adding a little bit of stevia but it didn’t help. I got the Blackcurrant. I didn’t like that it had a weird taste like vitamin pills or effervescents medicine pills. Maybe I just didn’t like the specific flavour, but i wouldn’t risk paying again for another flavour to not like it again. Love the idea tho, wish it was more tasty, maybe not for me

Hi Stavroulis!
Thank you for giving Fuse a try and for sharing such honest feedback. We’re glad the shipping, the packaging and the ordering process worked well for you.
We’re sorry the Blackcurrant didn’t taste right to you. Taste is personal, and flavours can differ a lot from one to another, so we hope you may give a different one a chance someday.

Not tasty
Delivery was fast. The flavors are tolerable, but right at the edge of what I'm able to swallow. Tastes cheap and has an aftertaste. I'll test other companies, definitively not a repeat customer

Great Product, comparable to any energetic drink
If was surprising how strong the it was. The "hit" is similar to a redbull but it takes longer to hit, around 20-30 mins and it last longer. So far the flavours has been great and I loved that you can have half a capsule if you don't want an strong hit.

Awesome product, but I'm having issues.
Great product, awesome flavors. But I don't know if this is just a production issue but my tablets have started not dissolving properly and leave chalky fragments in my drink. Its around 1 month ago since i bought this batch and I hope its just this tube and not the other 5. I'm storing them somewhere dry and it just happened today. I threw the first one out and tried a second one, still doesn't dissolve properly.
The whole point of buying this in bulk was to save money on energy drinks and coffee, but if i have to throw them out, then there goes the point.
Would love to hear other opinion on this.

Hi Benjamin!
Thank you for your detailed review and for the kind words about the flavours. We’re sorry to hear that your tablets aren’t dissolving properly, especially after you made a bulk purchase to save money. That’s not the experience we want you to have.
Since you’ve already tried two tablets with the same result, we’d really like to look into this for you. If you haven’t already, please contact our customer support with your order details and, if possible, a photo of the tube and the tablets, so we can sort this out as quickly as possible.

Fast delivery.
Fast delivery.
I ordered many tubes of Fuse on my 1st order. So far I drank only the mango flavored and it is very nice. I love it.
I originally ordered from WaterDrop but my order never reached me after almost a month and they refunded me. I dont want to take the chance again by reordering. So I ordered from Fuse and I am glad that i did. Order was easy and delivery was fast and seamless.

I like it
I like it, I enjoy all the flavors in the 350mL range. I intended to use it for the gym but the bottle is small, should be at least 0,75 to 1L and I would need to put two tablets in the drink that size and that's a lot of caffeine in that case. So I just use it for lunch, i really like it and I there is all kind of flavors that aren't boring

Hi Diogo!
Thank you for your review! We're glad you enjoy all the flavours and that Fuse has become part of your lunch routine. It's great to hear that you like having such a variety of flavours that never get boring.
Thank you also for the feedback on the bottle size. Since each tablet is made for about 350 mL, a larger bottle would need a different approach to the caffeine amount, so we understand your hesitation.

Great product, when I drank it I felt so happy and started laughing. But a few hours later my feet began to smell… not sure if it was related. 4 stars, wish it had bubbles pop

If you’re missing some bubbles, you can try mixing your Fuse with sparkling water for extra fizz.

Delivery was fast
Delivery was fast, taking less than 7 business days. I ordered 4 flavours, with blackcurrant being my favourite it tasted great. Blue raspberry is also a really good choice.
The apple flavour was okay, but it didn’t have as much flavour as I expected. However, I have to say the peach iced tea was probably my least favourite. The taste was a little too chemical for me and didn’t really resemble peach iced tea. Maybe it just wasn’t my cup of tea.
Overall, I think the products are really good. The price is very affordable, and they’re a great alternative to the energy drinks currently on the market. I’d definitely consider ordering again, especially the blackcurrant and blue raspberry flavours.

Couldn’t recommend
Couldn’t recommend.
Yes it gives energy without the crash. But they don’t seem to understand the drinks should taste good too.
At best half of the flavours are drinkable. Not pleasant but drinkable.
At worst the other half aren’t drinkable. Completely disgusting and do not taste anything like advertised.
Got the deal for a “free” bottle and can’t believe they’d usually charge £19.99 for something you can grab out of a discount retailer.
Packaging shown in adverts shows a nice box, individual section for the bottle all nice and clean. Reality is a cardboard box everything thrown in. No packing at all. Tape and send.
A classic example of a company spending most of their revenue on advertisements to seem better than they are.
Checked out a competitor afterwards and can say there’s better options out there if you’re trying to cut out energy drinks and fizzy drinks.

Hi S Farnsworth!
Thank you for taking the time to share such detailed feedback. We’re sorry to hear that so many of our flavours didn’t meet your expectations, as taste is a big part of the experience we want to offer.
We’re also sorry that the packaging and presentation fell short of what you expected based on our adverts. We understand how disappointing it is when the actual experience doesn’t match the impression you were given, and we appreciate you being honest about where we’ve missed the mark.

Delivery was delayed / bad product
Delivery was delayed. I got an email from FUSE saying my package was sent, but only 2 days later, I got confirmation from the carrier that the package was electronically admitted. So basically, they were lying, but whatever.
The packaging was not adequate and was destroyed. Generally, the carrier would be responsible, but the material used was also just bad.
And on top of all that, the taste really isn't it. I have Blackcurrant, Peach Ice Tea, Apple and Strawberry Lemonade. None of them really taste like the real deal. I tried it with sparkling and non-sparkling water, cold and at room temperature; it just tasted like artificial sweetener.
One more thing: you have to drink it within like 15 mins; otherwise, it absolutely starts reeking- probably the vitamins or something- but it tastes absolutely awful because of the smell.
The caffeine is not really noticeable, but that might be due to the L-Theanine.
All in all, I'm very disappointed and cannot recommend this product at all. A lot of fake/untrue marketing went into this

Hi Christian!
Thank you for taking the time to share such detailed feedback. We’re sorry to hear that your experience with Fuse fell so far short of your expectations, from the delivery updates and damaged packaging to the flavours and overall drinking experience.
We understand how frustrating it is when a product doesn’t live up to what you expected based on the marketing.
