The plastic tray that the rubber straps slide through is very thin and prone to cracking when you try to tighten them.
I’ve found customer support to be quite good, but experiences vary.
I don’t think the PM is practical as it is shipped. I find it too uncomfortable to wear as advertised, and 20 minute sessions are better served with heavy weights.
I, too, like the idea of overnight PE except for 2 big, bad experiences:
1) Once I left a loose tournique on for an extended time (40 minutes), I had done this in the past as a gentle ulie. I forgot to check, and when I looked down….my package was paper white!
2) I left the PM on while going to the movies, 2 hours later my dick had slipped a little, the glands had “folded” under the strap, and a crease mark was left on my head (it went away after a few weeks).
All this is to say that circulation is very, very important. I believe Bib has mentioned that tissue death starts to set in after 17 minutes if circulation is eliminated. Anytime you clamp or connect anything to your penis, there is a chance that something might get pinched or squeezed shut that you are unaware of. I personally believe anything that clamps on your dick for longer than 15 minutes begins to be a gamble.
