I feel so dumb sitting here thinking you were talking about the connections. Like yeah they're supposed to be round for ease of insertion. But also could tell something was off cause they usually point in parallel directions. Then I noticed the black dome they are attached to.
Please bring this to a proper site for disposal, that thing is like a flaming poison bomb at this point.
Last year mine conked out during a 100+° day. I tried everything! I'm talking cold(ground was still hot so it was actually a cool shower) then frozen water bottles in my pits, crotch, and neck. I ended up going to a cheap motel for the night and discover my door knob was actually hotter inside than out.
