Good but I’ve gotten older & don’t c as well so I like digital that stick on outside.

Completely botany, strong suction cup and accurate temperature readings.

This is one of the many thermometers that I have bought from aquarium co-op, the ones in the LFS don’t even compare. I’ve had these in my 10g, 20g, 29, and 40 breeders, and they have never let me down. I just got another for a 29g that I am using in my work office. You should be able to see the bottom of it in the top corner of the tank. They look good, are very cheap, and don’t disappoint. I trust this company 100%! Thank you Cory and the gang!

Broke and deposited small metal (lead?) pellets all over my new tank. Didn’t last an hour.

The glass thermometer is a LOT better then a sticky thermometer

I wanted an "analog" thermometer to supplement my digital thermometers so I wasn't completely dependent on batteries. This is a nice, inexpensive option. The numbers are small, but it is still easy to look closely and see the temperature. I am adding these to all of my tanks.

This is the second thermometer of this brand I've had and I couldn't be happier. I have one in my 10 gallon betta tank, and my 20 gallon high cherry shrimp and snail tank. They last forever and have tested pretty accurate against a digital thermometer. I'm getting ready to set up a 40 gallon breeder here in the next couple months and I will definitely be buying two more of these to have on each side of the tank. Thank you aquarium Co-op :)

This thermometer is worth it! I didn't want too much unnecessary electricity around my tanks so I went with two of these. Very accurate and easy to read, plus it doesn't take up much space :) Aquarium Co-op provides great packaging to protect products in transit. In my experiences, this company definitely goes the extra mile, and I'm happy to support this business. (P.S. the beautiful java fern in the back is a FOURTH of the one I received from Aquarium Co-op two weeks before!!!)

It works ok, but it is kinda hard to read. I have a very similar thermometer that I think is easier to read. Here the aquarium coop thermometer is on the left and the other store's is on the right. The darker markings and darker green area is harder to read and it's hard to tell if the numbers go with the line above them or below with the AC one.

Gives me peace of mind that my heater is still working. I have one in both of my tanks. I love everything from Aquarium Co-op and have learned SO much as a new fish keeper!

Measures temp accurately and sticks well to tank

It works great, now I'm going to go order a second one for my new tank.

I have one of these in every single tank I own. They work great! I didn't like the green area at first, but like today when its close to 0 F outside, I like to be able to quickly glance while I walk by my tanks that are by windows first thing in the morning. I'm not looking for a specific temp, just to see that its not fluctuated out of the green zone. So in the end, that's a feature that I have come to appreciate. These are $8.99 at my local fish store and $4.99-$6 at my local Petco's. So while you're ordering from Cory, don't forget to throw one or two of these in your cart before checking out. That's what I do.

Markings are very small and not easy to see with my 79 year old eyes. But it seems to give me accurate and steady readings. I have a stick-on digital reader at the other end of the tank, and it largely syncs with this one.

Got this as a 4th reference for tank temp. Accurate

Ended up not using it on my tank but it works perfectly fine

Simple and accurate!

Good little thermometer. I just use the camera on my cell phone to zoom in and enlarge the image of it to help me see the lines. I've used it to check the temp on replacement water and to take the temp of a container of water in another part of the house where I'm considering a second tank. Very helpful

This is my first order after hearing about Aquarium Coop. The work ethic and practices here led to me trusting these products and I am more than satisfied with my order and delivery time. Truth be told I'm already assembling my next cart. Cheers!

I trust this glass thermometer. Digital thermometers are notorious for being precise but not accurate (e.g. they will tell you the temperature to a tenth of a degree but 2 degrees higher than reality). The suction cup works well to keep it in place in a readable position. The only thing I don’t love about it is that the “safe” range background is green, which makes it harder to read than the white part in the part I actually want to read.

Accurate temperature, suction cup doesn’t hold all the time

I keep one of these gems in each of my 5 aquariums. Simple to use. Great price. Accurate reading

It's a nice little thermometer. It's great that it has the "green" range from 70 to 80 degrees as our tank is in my son's room and that means he doesn't even need to read the temp, he just needs to see if it's in the proper range.

Works as it should. No issues.

Its just a thermometer hahaha.. but I needed ferts and forgot to grab one so I added it to the cart too. Everything came fast and I was super stoked to get an awesome sticker to put on my co2 tank. Thanks Cory and everyone who is a part of the aquarium co-op team.

Works great.
