Glass Aquarium Thermometer with Safe Zone Section and Suction Cup – for Tropical Freshwater and Marine Saltwater Aquariums

Good basic product clear to to read and doesn't take up a lot of room.

Only bin using for a week , so time will tell but im happy with it , price is cheap so cant complain , delivery free aswell . Also i no the temp reading is correct because i used my head an bought another cheap one for around same price from a different company on amazon an put both in tank an they have both got the exactly the same temp reading . So now i have a spare aswell . One was £3.50 other £2.50 cheap stuff . Shops in my area wanted 6 pound rip off .

Very hard to read but works well

Easy to use just pit it into the tank and it tells you the temperature is easy to read good quality good value for money

Does exactly what it should

Useless. Reads at least 4°C low. Luckily I checked to temperature with a different thermometer before my fish died

Purchased pack of 3, 2 were fine but 3rd one totally fails to stay attached to tank

Good
