I just checked all the new undeployed stock I have on the shelf at the office. 13 total, 6 from WAV, 7 from Streakwave, all received around the end of August. I saw no cracks and FWIW only Torx head screws. These have all been at room temperature, not exposed to hot/cold cycles or vibration like riding around in the truck.

I usually touch every new SM, but we were going through them pretty fast back in the summer switching customers out. These all came loaded with 13.2.1, so I told them to just set the region and click the default frequencies button and have at it. I can't say for sure if they were truly bad out of the box. So I'm not going to say "hey Cambium, WTF" if it was one of the guys being careless. But I got them from three different guys and they all said they pulled them out of the box that way. I found this last one on the shelf in one of their trucks while looking for the damn walkie-talkies they don't bring back in to put on the charger! That drives me nuts.

I am not looking forward to the idea of going out and inspecting all the 3.65 SMs in the field, although it sounds like you have more of them than me. Time to buy a quadcopter? Webcam on a long stick?

The larger screw heads would stick up a bit too far and not allow the cap to be locked. I've fixed many by tightening those a bit as suggested and it works fine. Probably had 80-90 of those so far. This one has one of the normal torx screws and one phillips head holding the bottom on. Got maybe 10-20 like that. And the phillips head screw isn't on the side with the cracks in the front cover of this one. So... I don't have a clue how this is happening.

Always in that spot and I have no idea why. They're obviously going to leak. I'm betting Cambium won't cover them under warranty either (and I don't blame them), but we did end up with one or two that came this way new out of the box. This one I think one of the guys stupidly tossed on the shelf in the truck. They're not worth sending in for repair. I'll just wait until one is murdered beyond repair by lightning and steal the cover. But I thought I'd ask this anyway... can we get these covers anywhere so I can just fix them myself?
