This was cool, but it wouldn't stick to my turtle's terrarium well. Smokey the cat ended up pulling it out, and it got shattered on the floor.
Don’t buy this thermometer

Hard to read and suction cup is no good. There are a lot better options out there. Purchased only to meet minimum for free shipping.
Bummer on this one

Some slimy white stuff comes off the suction cup when in the water a few days. Yucky looking stuff so I suctioned it out of the tank and good bye to the floating therometer. It was a pain anyway because it cannot be adjusted directionally to make it easy to read because the suction cup is permanently in place and doesn't allow swiveling the thermometer. I do not recommend this item.

Great little thermometer. Seems to work great. I just stuck it to the side of the tank and that was it. It is easy to read and see the numbers. It does not bother the fish at all.
Do Not Buy - Broke in Tank

I've had this for less than one year and it somehow broke inside the tank. Luckily it's not mercury but I had to deal with broken glass inside my tank. Do not recommend.
Does it's job

It's a basic thermometer just what I needed. I'm sure I'll need to purchase additional items for my aquariums.

I guess you could say all thermometers are pretty simple and the same. The same goes for this one. It tells an accurate temp, with a safe zone highlighted in a blue/green. I really like the suction. I don't like thermometers that you stick on the tank, as the residue after taking it off is horrible. The suction is strong and can be placed anywhere inside the tank.
