I use it for my work mail. I can’t speak to their privacy, but I think it’s ok. So far as I know they haven’t done anything stupid, and all the connections are only from my device, no cloud intermediary.
I do like that it allows you to only apply the ActiveSync policies to the app instead of the entire device. If my employer remote wipes my device, it only impacts the app.
While I generally agree, I must say that my Ryobi tools are doing just fine after 15ish years of use. Primarily the drill is what's used, and it's seen some shit but aside from a little cosmetic issue (rubber peeling off here and there) it's in great working order. I can afford better now, but I'm happy enough to keep what I've got.
I'm just a handy home owner, so it's not like I'm abusing these things.
