SunGrowDigital Betta Thermometer for Tropical Aquarium Fish, Yellow Color, Suction Cups and 1 Battery Included, 1 pc per Pack

Reads at 78.1/ actual 78.5.Simple. Functional. Like the yellow color. Battery compartment easy to access. Uses cheap button style batteries. Smallish read out. Hangs off the suction cup, so it points down, which means you have to bend down to read it.Does just as good of a job as my Fluval and Hygger for a fifth of the price.

Does not come with a battery, and it is off by 2 degrees Fahrenheit, or 1.3 degrees, or 2.3 degrees.... it varies. It is easy to read, operate, and does come with two suction cups. It does not, however, come with the battery that it advertises as included. I had to buy the button cell (LR44) separately. Not impressed by BOTH the inaccuracy in temperature reading and product advertising.

This comes in handy on water change day. This allows you to measure the water temperature before adding it to the tank. Helps prevent temperature shocking you beloved aquatic pets.

This product was really easy to use and is very accurate. I have been searching for one for weeks and so glad I came across this product because it was about 1/3 of the other companies prices. I have no complaints and the suction worked very well the first time but did fall off a few times, but haven’t had any problems since ! Super easy to use and read!

No wonder it is "79%" off. I was relying on this thing as my fish came today.Bad/Returned

I have bought a few different ones, and this one has been the only discount thermometer that is accurate! Not loving the color, but who cares if it works? :)

screen didn't work, only half of it worked. My money was refunded through Amazon.

I would just get a heater with a thermometer this one changed like 10 degrees every 10 minutes and it looked like it made my fish uncomfortable

Nice little bit of kit.Clear and easy to read.Suction cup on the thermometer itself is very strong, the interior one with the sensor not so, repeatedly comes away.I've buried under the aquarium stones .

Thermometer works as intended but was made out of really cheap material. Wouldve liked it more if it was built better but overall a solid product.

Fantastic product. This is my 3rd one, and wish I brought it first. Easy to install, love that is outside the tank so easy to read and it comes with a battery!

Shows reasonably accurate temperature, but doesn't turn off. You need to remove the battery.

Pas cher fait bien le travail et on très bien les chiffre
