Yes and no. LOL.
Personally, I don't like the terrarium liners unless you buy two or three so when your animal poops on it you can remove it and replace it with a clean one. But you said your come with real substrate so never mind. :P
These also come with a no-name brand heat matt. I much prefer Zoo-Med or another big name.
Most of the lids for these just sit on top and lock down with a couple spring clips, I have used these and personally I don't trust them. I sure they work ok though.
Also, these kits come with analog gauges which are well know for being inaccurate.
I guess what I'm trying say (the long way around) is that for the same money you can buy quality items, including a thermostat (Very important)
and digital gauges better suited to your reptiles needs.
As you can see from my list above that my new setup is customized for my Boa including a thermostat (very important again

) and digital Zoo-Med thermometers and Zoo-Med UTH that can be trusted.
I hope this helps, I know we got off topic a bit, LOL
