THE BEST COMPANY FOR CRYPTO COLD WALLET
NGRAVE IS THE BEST COMPANY IN THE CRYPTO MARKET TO BUY YOUR COLD WALLET.
THE WALLET IS 100% AIR GAPPED, WHICH MEANS THAT IS NEVER CONNECTED TO THE INTERNET.
NO WIFI. NO USB. NO BLUETOOTH.
NONE OF THAT.
ALL THE OTHER COLD WALLETS ARE NOT REALLY COLD BECAUSE YOU TOUCH THE INTERNET TO TRANSACT, EITHER VIA BLUETOOTH OR USB CONNECTION; STILL, YOU ARE USING THE INTERNET TO TRANSACT.
NGRAVE ZERO IS THE ONLY WALLET IN THE INDUSTRY WITH THE HIGHEST LEVEL OF SECURITY AND PROTECTION.
IF YOU WANT TO STORE THE WEALTH LONG TERM, THIS IS THE WAY TO GO.
IN THE END, SECURITY AND PEACE OF MIND IS ALL WE REALLY WANT.
I AM WRITING THIS REVIEW NOT BECAUSE I HAVE TO BUT BECAUSE I WANT TO, BECAUSE OF THE WAY THEY TREATED ME AS A CUSTOMER.
ESPECIALLY FOR THEIR CUSTOMER SERVICE.
AS I AM NEW TO CRYPTO, I HAD MANY DOUBTS, MANY FEARS, I DIDN'T SEEM TO UNDERSTAND.
LUCKILY FOR ME I MET BENE, A REAL CRYPTO PROFESSIONAL FROM NGRAVE THAT, DURING A VIDEOCALL, EXPLAINED EVERYTHING TO ME AND ANSWERED ALL THE QUESTIONS I HAD.
I REALLY APPRECIATED THIS ABOUT BENE BECAUSE IT IS TRULY A TESTIMONIAL THAT NGRAVE IS A 360' COMPANY IN THE CRYPTO SPACE, NOT ONLY GIVING US THE REAL COLD WALLET, BUT ALSO HELPING US AFTER WE PURCHASE THE WALLET.
I HIGHLY RECOMMEND THIS COMPANY, NOT ONLY FOR THEIR PRODUCT (NGRAVE ZERO WALLET), BUT ALSO FOR THEIR CUSTOMER SERVICE AND THEIR PROFESSIONALISM IN BEING THERE FOR YOU AFTER YOU GET THE WALLET.
NOT EVERY COMPANY DOES THIS.
THANK YOU NGRAVE, I AM VERY HAPPY WITH YOU.
Incredible customer support
Like a few others here, I had problems with my NGRAVE Zero device not charging, no matter what I tried. I reached out for some troubleshooting tips, and was amazed when I was offered a free replacement device. The team were incredibly friendly and understanding over emails and the support was second-to-none.
Despite the technical issues that apparently need to be addressed, I'm now a fan of NGRAVE and look forward to any future products. Thank you for making this otherwise stressful situation incredibly simple.
I'm shocked of how good they handled my battery issue.
I had an issue with my ZERO after not using it for over a year the battery wouldn’t charge. I tried everything: different cables, power sources, standby mode, even letting it charge for hours, but nothing worked. Considering how pricey the device is, I honestly didn’t expect much beyond basic troubleshooting advice.
But Jay from NGRAVE completely exceeded my expectations. After a few messages back and forth, they offered to replace the device entirely, no hassle. The whole process was smooth, and I had the new ZERO in just a 6 days.
This level of customer support, especially for such an expensive product, is incredible. Huge shoutout to NGRAVE for standing by their customers and making things right!
Product works great and the customer…
Product works great and the customer service is fantastic. They are always very responsive and helpful so I can highly recommend the NGRAVE.
This was horrible
I want to rectify my initial one star review.
After a couple VERY stressful days, I must say I got helped exceptionally well by Bene from the CS team.
I purchased one of the very first wallets, and apparently some of them have a battery issue.
So did mine. A very unfortunate timing, because I really needed my funds.
After I contacted Ngrave, I received a new wallet extremely fast. So, thanks Bene. Everything turned out fine.
THANKS

Set the ngrave up let it sit for a while tried to start it and now wont turn on. I plugged it into a wall outlet and charging light wont even turn on. Held the button for 10 secs and nothing. This is why batteries are a bad idea for a wallet.

Device only worked once. After a few months I wanted to use it again and it didn't work anymore.

Great product and fantastic customer service. Only thing I didn’t like was being stung import duty to the UK. Damn Brexit
great support
When buying a device that is a market leader which it is you also require great customer support.
Both times I've reached out to their support they've been quick to reply giving me as much detail as possible to help me resolve any issues that I had.
They genuinely care about you and the experience you receive.

NGrave Zero is by far the most secure wallet one could own.
NGrave Support is by far the best customer support I have ever experienced in my life.
NGrave software is easy to use.
NGrave software uses the same public key for all transactions. Anyone with that public key can see my wallet balance. Minus one star for that.
If privacy is not an issue for you, then I highly recommend NGrave.
As a novice and new to crypto I was…
As a novice and new to crypto I was advised to move my tokens off the public exchanges and into a cold wallet. One of be my friends cautioned me about the lack of support he experienced when he ran into problems with his wallet so this became a huge concern for me. Actually, it became the greatest concern of mine, knowing how tech unsavvy I am. I decided on the NGRAVE ZERO when I discovered their contact information, sent them an email and got an immediate response. I was sold, purchased the Zero and absolutely needed their help during setup and firmware update. I was guided through the entire process, and was sent links and videos to assist me. After successfully setting this up staff at NEGRAVE contacted me to see how I was doing and wanted to know if I needed any further assistance. What a great experience! Not only do I have probably the most secure cold storage device out there, I also have a whole team ready to tackle any problem I may encounter .
Amazing!!!
Amazing customer service and would highly recommend the ZERO, best cold wallet on the planet.
Great support with innovative product that works
They have a very helpful and quick support, which is good to have with a product that is not just like any other and needs some guidance at times. Once you get the hang of it, it is smooth to use together with the app on the phone or the laptop.
Only Cold Wallet I ever will use !!!!
The most secure Cold Wallet on the Market. I care more about Security versus how many Altcoins I can store. The Customer Service is just amazing, you always get an Answer within 1 Day. I'ts well worth the Money to protect your hard earned Bitcoin (Safings)
Great Job Guys
This is a great crypto/blockchain…
This is a great crypto/blockchain wallet, and the customer service is outstanding. If you have any questions, they will get back to you right away!
