Good review for BitHD wallet.
I like to read real reviews for products, and test devices myself.
I don't mind so much lack of support for many shitcoins, but if BitHD wants to compete with brands like Trezor and Ledger they need to provide PC connection.
Mobile app is good, but PC and Mac apps must be added.

Thank you for the feedback, we will consider to do this in the future. But currently, we focus on Mobile APP.

I know a lot of people who doesn't have a personal notebook or desktop computer. I have one, but I am a tech guy Smiley

However, I agree with you, it is important now.

In future it may not be that necessary. And this wallet has an interesting format, it is like a mobile hardware wallet. It is possible that they are thinking about the future when we will be carrying bitcoins like a credit card, and keep most of our btc stash in safety at home in a trezor or ledger device

I receive a wallet as well, but it is not in the same city as I am now, due to corona virus crisis... I will make my review in a few weeks

I guess we can work around this limitation with Memu or some other Android emulator.
Install app and use computer camera.
We are all tech crypto guys Smiley

Introduction

I was provided with a test unit by BitHD about a month ago. HCP has already unboxed the wallet so I am going to skip this part. Just for the record, I am not affiliated with BitHD and I was not paid to post or modify my review. A list of sellers is available at BitHD.com. At the time of writing this review, the device costs $99.99 + shipping with a limited warranty.

Hardware

The device feels surprisingly sturdy considering its thickness and weight (12 grams). I tried bending it a little and I believe it should withstand any stress while being in a wallet. On the bottom, there is a proprietary connector which is used only for charging. All the communication is handled via Bluetooth. The back is made out of aluminium while the front is plastic. On the front, there are two tactile buttons and a 128x64 OLED screen which is exactly the same as the Trezor One's except being a little bit brighter.



Note: Both screens are fully functional. The black lines are my camera's fault.

Software

Razor runs a modified version of trezor-mcu which was used by Trezor One until last year. The code is open-source and available at GitHub. This means that most of the actions that take place on the device (PIN entry, seed generation/recovery, confirming transactions) look exactly the same as on Trezor One. Razor requires BitPie app which is available for both Android and iOS. At the moment, it is not possible to use Razor with a PC and any third-party software.

The app dashboard has a simple design. The 'More' button reveals a few more options such as signing Bitcoin messages (available only for legacy addresses temporarily), address book, a list of previously generated addresses and a shortcut to the settings. It is possible to add those hidden features to the main screen; the existing shortcuts can also be hidden if you don't intend to use them.



The hardware wallet settings are hidden under 'Me -> BitHD Setting'. Here, one can change the device label (this setting does not affect the Bluetooth name), reset PIN, switch between Chinese and English, enable Passcode Account (which is basically a single passphrase protected account), wipe the device, verify the seed (without exposing it to the phone), upgrade firmware and do a few other minor things.



The device generates legacy addresses by default but it is possible to change the address type to both nested and native SegWit. It would be nice if nested SegWit was the default type in the future! The wallet supports pay-to-many, local labels, spending the whole balance, saving addresses in a address book and adding OP_RETURN opcode. There is no coin control; one cannot freeze coins or spend from specific addresses.



At the time of writing this review, Razor supports BTC, LTC, BCH, BSV, EOS, DASH, ZEC, USDT-ERC20/OMNI and DOGE.

Comparison with other wallets

Razor has a strong competition. It costs almost twice as much as Trezor One and Ledger Nano S. It offers basically the same features as Trezor One. However, Razor lacks support for some coins that Trezor One supports. I have also used Ledger Nano X for some time and both devices offer smooth Bluetooth experience. There weren't any problems with it during normal usage and software updates. The Nano X costs just slightly more (+$19), offers better altcoin support and a different security model.

There is a similarly priced and looking product - CoolWallet S. While the form factor is identical, it is a completely different device. It has an e-ink display which can display limited amount of information compared to Razor's OLED display; it uses a secure element while Razor has the same microcontroller as Trezor One and its software is not open-source.

Summary

Is it worth its price? Well, if you don't need a credit card form factor then there are cheaper or slightly more expensive alternatives which have a similar or even greater functionality (third-party app support, more altcoins supported, better hardware). However, if you are interested in having a hardware wallet in your wallet, Razor seems to be the most interesting of the very few options available on the market. Needing a small wallet and given the choice between CoolWallet and Razor. I would go for the latter one. Again, it all comes down to personal preference and priorities.

Feel free to ask me any questions. I also own Trezor One, Trezor T and Ledger Nano X if anyone would be interested in more detailed comparison between these wallets. Although, I don't think if there is anything more I could add.
