Review on 🐠 Boxtech 5 in 1 Aquarium Cleaning Tool Kit for Fish Tank - Stainless Steel Algae Scraper, Aquarium Net, Water Grass Clip, Sand Rake, 360° Rotation Brush - Ideal for 10-120 Gallon Aquariums by Jennifer Kiel

Handle and extensions are hollow which is good but the nozzles have no vent/drain holes. Most (very large) heads cover the pipes and if you have a deep tank this can limit control and accuracy. Other heads don't and make a mess when you remove them. If you lose your grip, the wand will shoot out of the water. The razor scraper is awful, doesn't even work. The brush is too big and there is no way to get the right angle. The works fork (the main reason for buying it) is large, too. If you don't plant stems in your tank, it won't help much.
