I ordered a rodent watering system from Reptile Basics along with some other stuff and when I got everything unpacked I was 1 drinking valve shy of what I had ordered. I emailed him and shortly after I got a package in the mail. I open it up to find he sent me 3 drinking valves (2 more than I had ordered) and a few extra T fittings. Absolutely would buy from him again. In fact I go to his site all the time just looking to see if he has anything new I might want to buy from him. Don't need anything, just looking for an excuse to buy stuff from Reptile Basics.
