[Q]: This thing does not tell you which app to download. I turned it on in range of WiFi and it would not connect regardless of which of the 3 apps I used. Thought that buying a cheap product was the way to go... you get what you pay for. In an age of cheap technology, it is astonishing that it comes with so little information. I am a reasonably tech savvy individual, and the fact that I can't figure it out speaks to the low quality of the product. DO NOT BUY!
[A]: negative

[Q]: Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should've know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.
[A]: negative

[Q]: The canisters are easy to use, and when you finish them, you can send them back for a refund of the deposit. I contacted customer service to get a shipping label, and they were very helpful and friendly. It doesn't hurt that the company is based in Ann Arbor - Go Blue!
[A]:
positive
