Hans Panel Problems?

Ok so I've been doing a good amount of research on Hans Panels and can find nothing but good reviews but can't seem to find anyone who uses them long term. Anyone here have any problems with them? How long have they lasted you?

It's tough to find some good info on Hans panels but mine (85 watter) are still working fine after a few months though I feel they run a bit hot in my tent. In the winter they're fine but now with all the heat of summer they seem a bit too hot. Maybe it's time for me to talk to Hans.

I have no complaints about my 85 watter, maybe a little warm like FJ said. I have my 3070's going now so Hans is just waiting til I fire it up this winter. They grow MJ real good, good for the money in my opinion.

5 of them running in a 4x4 tent, in a uninsulated room with 28-29°C day temp at the moment: no problems at all.
Temp inside the tent: 30-31°C max. They run pretty hot in there but flawlessly, since almost a year now...
