I don't know how all these people are struggling, I can only speak for myself but I love these ones! I split three tanks into two and all three are still working almost a full year later! The suction is strong (my geckos climb it all the time). It's hard to read from some angles, but generally when reading a thermometer I'm close enough to read it with no problems. Accurate readings (I have tested various thermometers/areometers from various companies and all readings are within 1 degree so I would say they are accurate). I definitely recommend this product! (and two for those who have or want a temperature gradient in their aquarium. Worked for me even in a humid environment!
