I've heard the same thing, works or it doesn't. I've talked to two guys and can say 100% their problems are installation and program related. It takes a while to program and get set up, like mentioned if you don't have it programmed right it will flip left and right constantly in waves or wind (like the old TR1's you would see at B10). If the compass isn't installed correctly it will do wonky things as it assumes it's in a place it isn't.
Another thing is not getting the steering tube in right and not getting the linkage set up right. If there is any binding it won't work well. Stainless is a must for salt water.
I don't know how many hours I have on mine, probably 100 conservative and the only problem I had was when I got too much fish slime in the remote and one of the buttons was sticking. That was fixed with soap and water.
It's not plug and play, they are designed to be installed and programmed by a dealer, so if you are going to DIY, set aside a day to install and an entire day at the lake and verify in wavy and windy conditions. There is a separate dealer menu you need to access to get at the settings you need to adjust. I have a degree in electrical engineering and it took me a while to install and program it to my boat. That said, once done it's flawless and entirely predictable.
It's a big system, most of the parts are the same across any boat and they are used in all kinds of motor yachts and sailboats. The kicker actuator and throttle are the only unique things. The display, both boxes, network and remote are common amongst any size boat.
I would say if you are looking for something plug and play, go with the electric bow mount. For me, that made zero sense but I know guys that use them and like them.
