Wilson Baiardo is all looks. We have 3 in our shop and each has had it's problems one problem that all of them had is the wire that connects the puller button to the machine over time got worn out and had to be replaced. Wilson in their new version now protects the wire with a plastic shield. Other problems we had is the base clamp locking spring got stuck or was slow to pop up so you really had to hold the lever to lock it. Last problem was the tool tray being too small, but wilson fixed that with extra tool trays and a small shelf under the too tray.
I string a over 20 racquets a day but never had the need to change the angle and height when doing mains and crosses so the ergonomic feature is an unused feature for me. I actually prefer to string on my gamma 8800 with my old babolat star 3 clamps.
