I love this simple to use thermometer for our fish tank, It is as easy as peeling the back and sticking it on the outside of the tank. The easy to read digital display is awesome. No more guessing whether the water is a temp or not. WE have been using it for a few weeks it works well and its fast and accurate. The price was amazing as well. Read more

This works great. It sticks on the side of the glass and is just as accurate as the ones that put a prove in the water. It’s easy to read without any wires. Read more

I got these to replace a strip thermometer that only displayed a temp once. What a waste! These are great! They come with extra batteries and extra adhesive. I put them in place. The immediate readings were several degrees high as checked against my instant reward thermometer. Fortunately the manual mentioned this. Within 10 minutes they had settled in and were reading perfectly. I like that they only display on demand saving the batteries. Read more

This works great. Just sticks on outside of tank and it goes off until you push the button! It's pretty accurate, usually matches my thermometer that I double check water with. I do wish it would stay on, light up , and give the read out all the time without having to push button... But, overall, it serves the purpose, and does fine. Read more

You just peel the sticker off and stick it on your glass tank. It seems pretty accurate and a good value for the money. Read more

This is a small, round temps reader that works great. It sticks and is easy to read. I’ve ordered one for every tank I have. The acrylic tank reads 3 degrees less than actual temps but easy to adjust. Read more

Very nice! Precise and easy to use! Just don’t plan to remove until you use battery up and dies! Cost is ridiculously low as you get a replacement battery in addition to one inside just remove sticker backing and put on straight and voila! I love it son my 55g perfect size on there! Arrived fast! Nice package only wish I bought the 2 pack for my other tank! Seems durable enough! Had it a few weeks ! Read more
