Inkbird IBS-P05R Solar Powered Wireless Pool Thermometer

Advertised as pool lights as well as wireless pool thermometer, so bought one. It came with zero level battery, so put it in the pool in 30degrees open sun expecting after full sunny day to see the pool lights at night as advertised. Nope - full first day the device was dead only registered with the controller after 2d in direct sun! Was sdtting for 3 full days in the pool in the sun and still no lights at night.

Found now that many web reviews say - common issue with inkbird termometer and support would exchange the faulty (so it works at night after the single day in the sun as everyone would expect for solar powered device which i have many including powerful led flood lights in my house).

Inkbird Support refused to action - saying it needs 7 (seven!) full days in the sun to see the light working, so it needs full 7 days of charging so it will work single night?

Requested to collect this not "fit for purpose" solar pool light for the refund - no response, starting credit card chargeback.

Dont buy from inkbird: pool light/thermometer devices are faulty and inkbird customer service just doesnt exist (happy to apologize but not willing to acknowledge the issue and exchange the faulty product)!
