I'm a first time froggie mom, and I was having trouble keeping the moisture levels right for Priscilla, my wtf. After some feedback here on the forum, I decided to get the exo terra monsoon system. I have to say I am really happy I got it. It was super easy to set up and works great. My one hiccup, the first system I bought was dead out of the box. But, I called the customer service line on the back of the directions and they sent out a new one with a call tag as soon as I faxed the receipt. They were so easy to work with, and very quick! So, my advice, keep as receipts, and don't buy one on craigslist unless you can test it first. The second system however is perfect!!!
