I accidentally overpaid in Bitcoin for an item I purchased from Altair Tech. Their customer service team responded promptly to my email and quickly issued a refund. I am extremely pleased with how professionally and efficiently the situation was handled. This was truly one of the best customer service experiences I have ever had—and I sincerely mean that! Please keep up the excellent work. I look forward to continuing a strong business relationship with Altair Tech.

I had a minor hiccup after receiving my Nano 3S unfortunately operator error and I am incredibly impressed with how quickly they responded to my request with suggestions! Within their list of suggestions was the “light bulb” one. 🤦🏼These guys ROCK!

Great price, great dock/stand for my Avalon Nano 3S. And the shipping speed was amazing. Nothing ever gets here as fast as this did from Altair. Will definitely keep an eye on the page to see what else they have that I need. I instantly shared pics of it and my praise for Altair on X. I rarely do that lol.

The new Nano3S that I bought from your store does not pair or connect with avalon family app. I tried connecting it using the included wifi receiver for two days but no luck. I have an old nano3 that connects with no problem. a. On IP address connection, It doesn’t connect even with the IP address shown on the nano display was used. b. The heater_nano wifi network also does not appear on my iphone wifi settings. c. When the nano3s for connection screen shows up, it also errors when the correct wifi address & password was entered. Please advise
