Last question for now, I promise!

So I went and got some stuff for my frog's new terrarium. I decided to get a fogger because I sometimes forget to mist and that's not good for her. I decided on the ReptiFogger because it looked like it would deliver the humidity well without it drowning the tank in water. However when I got home I read some horrible reviews on it. A lot of people said it quit working after 2 months and that's how long the warranty is for. Has anyone tried it? Should I risk it and hope it keeps working for many years or return it while I still can and get something else? (And if so, what is a good option?)

I also got the TetraFauna Repto Filter, which is like a waterfall/filter system. I got it because my old waterfall doesn't fit in the new enclosure (it doesnt have deep enough water.) I haven't heard anything bad about it but I wanted to get some opinions on how well it works? I am planning on creating a small river at the bottom of the waterfall that leads to a shallow "pond" for my frogs to soak in (tips on how to do that would also be appreciated..)

Thanks!
You guys are the best.
