"LOVE these thermometers."

I have kept aquariums for about 45 years. The suction works for a month at a time- in pool and hot tub circulation. I used to have a large hang in the side tank that you couldn't miss. Ambient room temperature measures 72. Now if it falls into a sink full of water, it's not a problem. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. I used these on a number of my aquariums that have discus fish in them.

"Perhaps it's my fault."

You can use the thermometer with or without the plastic suction cup. For the price I'll probably end up putting these in all of my aquariums. They are within a degree or two of other thermometers I've checked to compare them. I needed a solution that was not breakable and these do the trick! Only thing I don't love is how long the cord is. I'm pretty sure those reviewers have acrylic tanks. He acted aggressively towards it and so I ultimate ended up removing it due to that.

My 50+ eyes cannot read a regular tank thermometer without squinting. My only complaint is that they tend to be a one time use. You can not swivle the thermometer to face a certain way.
