Review on 🐠 HITOP Adjustable Submersible Aquarium Heater for 10-35 Gallon Tanks - 50W, 100W, 120W by Steven Dahl

Bought 4 x 100w heaters for my new aquarium, 2 broke on delivery. One of them sounded like bells in a box so I didn't open it and decided to return it, 2 were fine and not broken but the 4th had a big crack on the front of the glass which I hardly noticed because of the breakage was so straight it looked like a seam, but upon closer inspection I saw it was a deep crack in the glass tube near the heath base. I returned two broken ones and quickly sent Revain a replacement, but two of the replacement units were also cracked when looking through the plastic cover. if I hadn't seen her. Seems to me the whole batch could be damaged as they all had very similar cracks except for one bell which again was pointless to look at. However, I have two that work fine. , and keeps the water in the tanks at the exact level I set as well, but it's quite difficult not to break it 😬 At work, they're the best adjustable heaters, I just wish the handling and packaging were better. I would order again but had 4 broken ones and 2 good ones after replacing, I think I'll find the heater locally. Update November 2nd: The two heaters I was able to use are still working great. Maybe I'll try my luck soon and order more to see if they arrive undamaged. Of all the heaters in my aquariums, these two really are the best. In other tanks I have 12 Aqueon heaters and they are not nearly as good and cost the same.
