I guess you have to be careful which powersun you buy. The two we bought are not causing any pkc problems with our girls and we've had Goldie's in since early June and Rosie's for just under 2 months. We tried the reptisun 10 tube but it didn't increase Goldie's appetite like it did before we went to the mvb's.
Has Zoomed fixed the problems the powersuns were causing ?? Im looking to get one for the living room, so when my dragon is out he has a good source of heat and UVB.
I'm not sure. I think it depends on which one you buy. I was prepared to take one back if it started causing problems for our girls but neither one has yet.
