It does seem nowadays that you have to Test everything you buy while it is still under Warranty
Aint that the truth! They don't make things like they used to, for damn sure!
I can't believe the products comeing out these days that are sub quality from the start. It doesn't stop at electronics either, I've had issues with high dollar scopes and sent them back before ever mounting them on a gun. It goes all the way up through ATV's, Vehicles, and RV Campers.
If you don't think you'll get a chance to ring something out before the warranty expires, buy extended warranty. It's worth it these days. I bought a brand new 5th wheel camper a couple years ago, didn't use it for a year after buying it. Used it the first time and found all sorts of things that weren't right. I had to get pretty grumpy with the people at the dealership for them to honor the warranty (it was 1 month over)
