I'm using this company for many years now. I bought from them 4 bidets and I am always fully satisfied with quality, comfort, hygiene settings, and reliability. They arrive very well packed and they are pretty light, not difficult to handle and unpack. The system they use to connect to the commode is brilliantly simple. Just screw in a base plate with smart screw. These screws are also very well designed: you do not need to drag yourself under the commode and work in painful positions. The rubber part of the nuts for these screws will be pushed in the commode holes from above, and they swell inside while screwing. This is gorgeous. Then the true miracle is that you just take the seat (the bidet0 and plug it in the plate until snaps. This is all. The rest is connecting to water line and electric power, set the remote and you are done. it works simple, very efficient, silent and it has a wonderful blue light for night time. As i said, they are indeed very reliable, they work for years. it is a very good idea to buy an ionic filter for water (the same company) to give your nozzles more life time.
Only once, some time ago, it happened with an older model to start to leak from the nozzle, inside the commode. The company helped me to repair. They offered assistance and help live (by video chat), email, phone, they sent me pictures, diagrams, movies. They delivered the replacement parts quickly and good quality.
Every time I email the company or call them for help or advice (not often, and almost never lately) they are helpful and open and clear in all the explanations and recommendations.
I highly recommend their bidet!
