The U-bend fits perfectly with my 1.5cm glass tank. The stainless steel feels solid and the suction cups hold well. Easy to install and keeps the tubing secure without any movement during use.

Works great with my 6mm tubing. The medium size fits my aquarium perfectly. The connector stays in place and doesn’t shift even when the tank is in motion.
