Looks nice - doesn't work, zero tech support - Seek XR Focus Camera

I bought one of these last week, about the same time I bought a new Samsung Galaxy S6. The S6 is great, I can transfer files, I plugged a USB flash drive in via a OTG cable, and it works good.
Seek Thermal's app just tells me there is no camera plugged in. I contacted Seek thermal tech support, and the best they could do was ask me to try it on a different device. So I did, on a S5. Same result, so I returned it, brand new, never used. I never heard back from Seek thermal even though I repeatedly emailed them. So if it works for you, great. Just make sure you can get your money back when it doesn't.
