I put this on an Aero M4E1 lower to see if I like it. Have used Armaspec, Radian, and an assortment of other short throw ambi selectors beyond just standard Milspec stuff in the past, so I've got a pretty good frame of reference for how these things should feel and work.

There are several issues with this selector:

1) Complicated installation / design
If you are using a drop in trigger, like I am, you most likely need to remove at least one trigger pin to remove/install a safety. This selector introduces two additional tiny hex key screws to keep the levers attached that screw through the main shaft of the selector . They are a major pain to install. If you do any work on the internals of your lower (upgrading a trigger, replacing a spring, etc) these hex screws alone will add 5-10 mins of fiddling with a tiny hey key to get this uninstalled. I have plenty of aftermarket parts, and I believe that certain types of components (triggers, selectors, captured buffer springs, etc) available on the market are generally better than milspec -- sometimes by a lot. But all of the aftermarket parts I have are either easier to install/service or have a negligible impact to serviceability. These screws significantly increase the time it would take to strip the lower and replace a component. There are better solutions - Torx screws that go directly into the center of the selector shaft for instance.

2) Lever craftsmanship
The levers are functional but they look like cheap plastic, have
