I never tried this before, Secondly im seeing this site first time with few other devices and + without https link. I think its risky to order from this site
Secondly what is the purpose of this piper if we can make a paper wallet using Bitaddress.org with a random btc address? Why we spent our money on it?
Hmmm...I think you are quite right but I would say that they are reliable.
Also I would say that it's nice because you have everything in one device and using a printer (which often have a internet connection nowadays) could be risky.
