Reptile Heating Pad with Temperature Adjustment, 110V 7W Heat Mat for Reptiles Tortoise Snakes Lizard Gecko Hermit Crab Turtle，Under Tank Heating Pad (7W(5.51inch*11inch))

Works well and good size.

This is what my Hermit crab needed for the winter.

I got two to put under the tank for our hermit crabs a couple of months ago, they work amazingly. They keep it warm, not too hot. It has a temperature adjuster wheel on the on/off switch which is nice. Comes ready to plug in, easy to use, no assembly required. Great value! 10/10 would recommend.

It heats an area of the tank semi warm , the bottom area as big as the product. Does not heat whole tank as it shouldn't but It's okay. Has adjustable heat setting with no gage.

Bought for hermit crabs to promote humidity, but didnt work out. Product works, but maybe i didnt order correctly for my needs. Doesnt get very warm even at highest setting barely noticeable with 5 gallon tank. Note that this product seems to be only useable under the tank. Instructions state not to use adhesive or tacks. More suitable for thin substrate layer

This kept my hermit crabs warm in the winter

Actually ordered another one. They worked out great for my ball python snakes. Love that they have a thermostat on them to adjust it up and down

I bought this for my 10 gallon hermit crab tank. It works perfect and does exactly what I need it to do. Just used electrical tape to secure it to the side of the tank.
