"Suction cups are okay."

I've checked it against two other thermometers that are accurate. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Works well in my betta tank, but provide a couple hours for it to read temp changes. When and if we run out of this batch, I'll instantly order another batch. You dont HAVE to stick the display onto your tank. Instead she sent a new package of two, both of which work. This company is taking the long term view of how to do business right.

Fluval 11206 Final Thoughts

"2-degrees."

I just wrote it off as a minor loss. My poor fish was in 86 degrees water for a month. Then is started to give a low reading, and it is not reading the correct temperature. Now that the chickens are grown, I have one out in the coop as well. 6F all six took about three minutes to read between 88. I've checked it against two other thermometers that are accurate. All were Close enough for a fish tank and other uses.

"Great product!"

The non-working ones still provide 2 batteries each AND. In this scenario it would probably get knocked loose a lot. Love it, it's easy to read and keeps an accurate temp. And is easily hidden behind a plant. Love it, it's easy to read and keeps an accurate temp. He acted aggressively towards it and so I ultimate ended up removing it due to that. Far more accurate than the usual small glass ones or external LCD strips.

"It sticks very firmly."

I needed a solution that was not breakable and these do the trick! I have this thermometer on all my tanks. The suction works for a month at a time- in pool and hot tub circulation. Since it is a mercury thermometer, it is very accurate. My 50+ eyes cannot read a regular tank thermometer without squinting. Ordered three of these and they do the job. I just wrote it off as a minor loss.

The suction will never be the same. He was moving slow in the winter and we realized he needed a heater! 6F all six took about three minutes to read between 88. It started working as soon as I put it in and has been working ever since. Instead she sent a new package of two, both of which work. For something so cheap, they are working remarkably well.
