Oh no, that was just an example !! I don't use theirs, I think they only have locking ones.
I wanted you to see the type I use. Reptile Basics is a great company and I wouldn't hesitate buying from them. They also sell that F10 Sanitzer that is great.
There are a lot of sellers on ebay as well, but I think that is mostly chinese stuff. What is important is that you have good stainless steel, so it will last
Yes, I like 16 inch. Anything longer is overkill and makes it harder to balance everything. Anything shorter...well, if you have snakes like I do that come shooting out of their tubs as soon as you open it...lets say 16 inches is better then 12, haha.
I like that length. I guess it depends on your snakes, etc..
