Booster Theme Reviews 201

I purchased the Booster Theme in November 2025, expecting a premium experience. After already paying for the premium theme, I was charged an additional $1499 for their “Premium Store Setup + Speed Optimization Service.” Unfortunately, this turned out to be one of the worst services I’ve experienced.

The overall process was extremely slow and inefficient. I initially spoke with Ms. Jenn over a Zoom call, who then introduced me to Milven. I clearly explained my requirements and expectations, but despite that, the results were far from satisfactory.

What’s frustrating is that today there are so many AI tools available—like ChatGPT, Claude, and Canva—that can help create high-quality banners and visually appealing pages. I even provided images and clear direction, yet they still couldn’t deliver properly.

For the amount charged, I expected expertise and efficiency, especially from a company behind a well-known theme like Booster. Instead, it felt like a complete waste of money.

My honest advice: don’t spend extra on these unnecessary add-ons. You’re better off building your store yourself using available tools, or simply choosing a more affordable theme directly from Shopify.

Great Results, looks amazing we are very happy

I recently bought the **Booster Theme** for my Shopify store, and it's been fantastic so far!

The loading speed is seriously impressive—pages feel instant, which has already lowered my bounce rate noticeably.

With over 40 built-in features like upsells, urgency timers, and trust badges, I've boosted my average order value without needing extra apps.

Customization is super straightforward with the intuitive editor, and I set up beautiful product pages quickly—no heavy coding required.

Customer support responded fast when I had setup questions—definitely worth it for anyone wanting real conversion gains! 🚀

Milven (my project manager) was excellent. He was communicative and always happy to work with what I wanted.
The initial draft of the store did have a few little issues, but these were ironed out without any hassle pretty promptly.
The only reason this isn't getting a full 5 stars is because the store isn't usable right now. It was incredibly slow and clunky (more so than my original store!) - that being said, it's been explained to me that this might be more due to the images being used rather than the theme itself. I was just thought that having paid for a premium set up it would include all of those optimizations and it turns out it doesn't. That is an extra charge, which was a bit disappointing... but otherwise the store itself looks good, customer service was great and I found the theme really easy to work with.

Excellent customer service, Klea resolved an issue quickly. Further the theme is great, with excellent loading speed - I'd purchase again.

Fantastic customer support. Klea and her team have been wonderful. Very responsive and helpful with detailed help

I can’t thank Milven and the Booster Theme team enough! They’ve done a fantastic job with my recent website update, and the transformation is incredible. They took the time to understand my vision and brought it to life. The site looks more aligned with my brand than ever before. Their communication and support throughout the process were outstanding — always responsive, helpful, and committed to getting everything just right. I’m truly grateful for all their hard work. If you’re looking for a theme and a team that delivers great results along with great support, Milven and the Booster Theme team are the best. Highly recommend!

First of all, the customer service is really poor. They do not give clear instructions and take very long to reply.

Secondly, most of the theme is not able to be translated without going into Liquid. The support says this is possible but are unable to give any clear guidance as to how.

After struggling for months to try to solve the issues, we gave up, asked for a refund and were faced with an automatic reply that we can't refund. That's poor customer service. I'm never going to recommend this theme to any of my colleagues in the e-commerce field.

Great customer service! My issue was fully resolved within one to two days, and so far I’ve always received a working solution for every problem I’ve had. It’s not always something that can be fixed instantly in the live chat, especially if the issue is more complex, but the help center with the AI and chat support is very effective for basic or common questions. For anything more advanced, the case is passed on to technical support, and they’ve done a really good job for me every time.

The customer support is not great at all to be honest, and a lot of the features are buggy with very little customization. When trying to use different features, a lot of the time they straight up do not work and customer support will give you little to no help.

I purchased the lifetime package with Booster Theme. I have been in contact with support MANY times. I have to say that their support has been OUTSTANDING. I just want to say thank you.

Booster Theme has been my go to theme for any store.

The theme is easy to setup/customize and their customer service is pretty fast and helpful.

I strongly advise you never to buy this theme. Since my purchase on September 28, I immediately reported a critical bug: the buttons do not work, and it gets even worse if your site is not in English (translation issues, multiple blockages).

Their support claims to reply within 24-48 hours. The reality? It has been 5 days and I am still waiting, with nothing but empty promises that "it will be handled soon." Today, October 2, I still have no solution, only repetitive, useless answers every single day.

Bugs encountered:

Buttons without any text.

Add to cart not working.

Serious problems as soon as the site needs translation.

The customer service is nonexistent, or worse, mocking. I even doubt the authenticity of many of the positive Trustpilot reviews, because based on my daily exchanges with them, the way they respond is simply unbelievable.

As a result, I have lost valuable time and my business is blocked. Avoid this theme at all costs if you want to move forward and not get stuck.

Love this theme. It beats Shoptimized hands down for ease of use and have not had any major issues with it. I was having trouble with a custom revison to my store and support solved my problem for me. It did take a few days but the fix was exactly what I asked for. Couldn't be happier with this theme.

Klea and the support theme have been extremely responsive and helpful in answering our questions re the various themes and set-ups. Great job

I’ve seen some mixed reviews about Booster Theme and their support, but my experience has been great. I’ve received timely responses, and the team even delivered a custom upgrade to my theme. They’re responsive, knowledgeable, and genuinely helpful. I’m already considering the support upgrade once my first year is complete.

As the owner of a 15-year Shopify Partner marketing agency, I'm thoroughly familiar with the top themes & apps. As an agency, there are many reasons we rarely recommend themes outside the Shopify theme store.

In fact, Booster is the first!

Not only is the theme incredibly fast - a must for a client recommendation - but the included functionality is quite good.

Add to that superb customer service - a rarity among theme makers - and our 5-Star rating is a no-brainer!

Excellent Support from the Booster Team!
We had 3–4 issues related to our theme, and the Booster support team was incredibly helpful throughout. Their responses were prompt, and all issues were resolved within just a couple of days. We're really impressed with their efficiency and dedication. Great team, great job—highly recommended!

🌟🌟🌟🌟🌟 Absolutely Outstanding Service – Truly Above and Beyond!

I cannot recommend Booster Theme and their incredible team highly enough. From the moment I purchased the full setup and design service, I was met with professionalism, speed, and genuine care for my project.

Milven, my project manager, has been an absolute rockstar throughout—always responsive, patient, and incredibly skilled. Every request I had (and I had a lot) was handled promptly and accurately. From homepage enhancements, GIF placements, variant image fixes, custom page builds like "Our Story", to advanced tracking setup with Klaviyo and Google Tag Manager—they nailed it all.

What really stood out is the human touch in their communication. I never felt like “just another customer.” They took the time to understand my goals and offered practical, expert advice to improve my store’s performance and design.

Even when there were small hiccups (like the email popup integration), they were quick to provide helpful alternatives and solutions.

Thanks to the Booster Theme team, my Shopify store looks and performs exactly how I envisioned it—and then some. This was easily one of the best investments I’ve made in my eCommerce journey.

If you're on the fence—don't be. Booster Theme is the real deal. 10/10 service, 10/10 results.

Klea and the team at Booster Theme are great to work with. We have a shopify store that uses their theme and it converts extremely well. They've got great support too. Highly recommended.
