Review on 🐠 Secure and Convenient Aquarium Soft Tube Fixture Holder for Pump Hose by Jeff Chisholm

One piece plastic, switch screws to secure tubing to aquarium rim as well as switch to the other side to fully secure the probes (almost?). I measured the maximum size of the tank rim at 14mm and the diameter of the inner circumference of the probe at just over 7mm. Used for dispensing hoses and attaches/holds the dispensing hoses with no problem. Screw knurling decent size. No worries or problems. However, it arrived in a padded envelope with no protection - I see this as a potential problem if a small order breaks in transit.
