At first glance it looks like it'll function fine.
One very big issue is the pipe leading into the threads. This will FALL OUT and cause a major leak. I had to hot glue mine for it to stick on, and even then it'll not be a permanent fix.
Another issue is the weight and gravity that causes said issue. You need a support for both the 3-way connector and the other 3 pipes. Otherwise, gravity and water pressure will pull down on those pipes and it will slip off. Absolutely 1/10. If I knew this, I would have never purchased. Who designed this?
Sure, it's relatively simple and easy to install, but the main function has too much problems. Highly do not recommend.
Depending on your setup, the absolute BEST scenario is an up/down setup where pipes are connected straight down from your sink, and drain is straight down. No wall drainages, no grinder accessory, no angles. Any sort of angle or gravity will cause the pipe to slip out. Very bad design. Please save your money and purchase something else. I would use a more adhesive material or substance on the slip ends near the threads, so it can stay on even with an angle and gravity.
