Review on 🐠 hygger Aquarium Gravel Cleaner: Quick Water Changer & Siphon Vacuum with Air-Pressing Button & Hose Controller Clamp by Crystal Reed

I have 11 aquariums and am using Hygger heaters and other products with no problems but this one is an exception. The trigger design looks nice but isn't functional. I used the product originally purchased and then tried the replacement supplied by Hygger so I'll label them product 1 and 2. Product 1 was a pain, it took me over 3 dozen tries with the trigger pull to get the water to flow then too slow then no. Hygger's customer service was great and sent out a newer, improved model. They ask if I can take the old product apart to see if it's clogged with too much sand. I did it and no obstacles throughout the product. I finally got a chance to try product 2 tonight. Improved trigger action, but still took 20+ pulls to get the water moving. Completely cut off the water flow and it will stop working and need to start again, more than 20 trigger pulls. I ended up with an old Kugelrohr which I will use.
