I like the Elander 17rd mags as well, but have had consistent, reliable results with my CProducts Defense mags from the start.
The straight-bodied 15rd mags were never meant to be made that way, and should have been destroyed or recycled, but were poured onto the market after being rejected by AA in the beginning.
Bill Alexander looked at the case taper of the Grendel when specifying the magazine body shape and dimensions, and determined that you really do need a curved magazine when you exceed 10rds capacity. For some reason, pallets of straight-bodied 15rd mags were sent to him, which he tried anyway, but of course failed and were sent back.
They popped up on .44mag after that, and many of us bought them unknowingly. As long as I only loaded ~6 or less rounds in them, they worked fine in my original carbine, which didn't have an upper with M4 feed ramps. In my Lilja 318 Grendel build, I de-edged and polished my feed ramps, matching them to the M4 ramps in the Aero no-FA upper. I discovered that I could load the straight 15rd mag to capacity and it seemed to work just fine, but I wouldn't expect those results in everyone's gun and would only recommend buying the curved mags if you go over 10rd capacity.
I fed multiple CProducts 25rd mags to some forum members at BoomerShoot for 3 days, and there were no malfunctions that I witnessed. They had 2 cases of ammo from AA for the event that turned into piles of brass like an M240 position.
Also, in my DM Courses, I've seen a lot of 25rd CProducts mags and no feeding issues with them.
