Is it safe on a plastic tank?

Answer by Chewy • Sep 01, 2019
If applied correctly it can safely be placed on plastic.

Is it safe to put 2 of these on a 10 gallon glass tank?

Answer by Chewy • Jul 27, 2018
This heater is intended for use on small tanks and it's not recommended to use more then one heater on a tank.

How big is it?

Answer by Chewy • Sep 01, 2019
This heater measures approximately 4 x 7 inches.

Do you use it on the inside or outside of the tank? I want to get this for my garden snail tank.

Answer by Chewy • May 20, 2018
The heater should be placed outside of your terrarium.

Not working as described.

Doesn’t work as described. The peel off sheet was not fully fastened when I got it out of the box. That side, by the plug in, does not stick to the aquarium

Doesn’t work as described. The peel off sheet was not fully fastened when I got it out of the box. That side, by the plug in, does not stick to the aquarium. My other heating pad sticks fully to the glass, so in comparison, this one is defective. I would like a replacement.

Good lil heater

Good little heater, not meant for a big tank. It does start to peal off - I had to put a piece of duct tape to hold it in place.

Does not work at all

This heater does not heat up my sons hermit crab cage at all. I'd give it a 0 if I could.

I purchased this one before.

Keeps hermit crabs warm

Only reason I gave a four star rating is it doesn’t like to stick to the bottom of the tank very well. Keep having to press it back on.

This hermit crab heater is best we have found on the market. It's easy to use and we have our crabs in a hamster cage vs glass kind. We use stones and sand and these heaters make it nice for the crabs without being too hot or burning bottom of cage

Not sure what to think

I have two of these on a 5 gallon tank, it still gets no warmer than 71degrees, room is set to 68 degrees. The aquarium is covered. I'm baffled. They are both warm

I have two of these on a 5 gallon tank, it still gets no warmer than 71degrees, room is set to 68 degrees. The aquarium is covered. I'm baffled. They are both warm to touch but if each one only raises the temperature one degree, I'd need four more to get the temp I want?

We keep our house pretty cool. Ordered this for our hermit crabs and they cuddled right up to it. However it does not stick as well as I’d like. One corner kept falling off so I pushed it against the wall and that works.
