LCD Digital Aquarium Alarm Thermometer, Large Screen Transparent Fish Tank Thermometer, Always Monitoring Your Water Temperature - Fast & Accurate - No Messy Wires

Its as good or better than more expensive products.

I like it so much had to have one for each tank,they look nice and are easy to read. I was able to remove one off a tank that i was not using and reattach it to another tank without a problem. However, I took one star off because they seem to be off by +/- 1 degree, both tanks are at 77f accornding to my calibrated thermomiter and both read about a degree colder , but they work and are easy to read, over all I like them.

While it's a cool looking display, the one that I received had multiple issues.The temperature reading would go out then blink back in. Acquisition is difficult at certain angles, and the worst flaw is the battery seat/cover. The battery doesn't seat securely no matter how you adjust it which lends to poor contact connection and display failures. While not particularly hard to change modes or set, it comes with zero instructions which may confuse some users. With these experiences I cannot recommend.

This is a simple product that doesn't show or explain, how to put the battery in...no obvious place for it on the device...sending it back if I don't get an explanation within one day! Finally got some minor instructions on changing out the battery. The cover you need to pull down is extremely hard to do without using a screwdriver or something to aid your fingers. Even after changing out battery the screen was blank. So, I would say this product was defective and the manufacturer was very hard to work with. Don't buy this product, there are too many others without this products problems!

Nice little thermometer, have one of these on each of my three tanks. Nice simplistic design and blends right in with the tank. As far as I can tell they're accurate enough within a degree or two. Only thing that I will advise is the battery life is not so hot, maybe 2 months before you have to change it. So just grab a pack of batteries to have on hand, other than that good product.

I used to use this thermometer on all my fish tanks ( strip ones),some times I wasn't sure if they were working right,now with this other thermometer game changer,thank you guys for this new concept.

I’ve had this for about 2 months and I’ve already had to change the battery. It’s a little hard to read the temperature at times or have to be right in front of it. I have it at the bottom corner of my tank so maybe that’s the reason. But it still works and does the job.

Easy to read and very convenient.The only thing is that sometimes change itself from Farenheit to Celsius.

Es algo pequeño así que no es como que vayas a ver tu pecera a través de el,pero aún así es muy estético y funciona a la perfección

Works great, looks nice , easy to read. I have 3 now.

This was great to be able to easily see my tank temp but once the battery died, it was impossible to replace the battery. It would not stay in place and stopped working since the battery would lose contact. Very disapointing.
