The guests' feedback, hoping to help your choices.
The locks with the zigzag kind of locking cuts that most adjustable stems have. Set it once and forget it. It works great. My wife has put 700 miles on hers without adjusting or retightening anything.
Warning! This unit has "notches" for each of the angle positions, it is NOT on a sliding scale. Be sure you get the notching correct before you tighten it up, or you might ruin the notch setting. If you do not get the notch setting correct, the handlebar will wobble ever so slightly.
Because I've been having shoulder pain, I wanted to bring my bars up and in to reduce strain. Since I wasn't sure what position would be right or how long I'll face this, I wanted an adjustable stem. It is heavier because it has that joint in it. It does of course take (actually two sizes) hex wrenches to install and adjust. It does NOT require disassembly of the handlebars and I did NOT require additional spacer rings for the stem. So I was able to install it myself without complications.
I don't think you can beat this for the price. I ordered the 100mm with 25.4 mm handlebar clamp. Put it on my Giant Revel. Works great!
