I bought these for my isopod bins, because I needed something small that I could suction onto the lid. These fit perfectly, and after a little bit of finessing, the suctions hold pretty well. They only don’t get 5 stars because the battery on one of them gave out a couple weeks after I got them, which was kind of frustrating. It’s a good thing they came with extras.
Bought this two pack because they were priced right, digital, and they came with suction cups. So far only one is still working, it’s been a little over a week since they arrived. I’m using them in room temperature and high humidity environment ( over 90%). The one gave out after about a week and the digital display is only showing half of the digits. I’m hoping it’s a fluke, as they are nice and well priced.
