Great review as always. You present your reviews in a clear and concise manner and you speak very well.
Yes, there is an auto shut-off. For the price, I'm giving it a shot. I've got aimpoints and eotechs and while I think they are excellent products, I'm hoping to find a less expensive alternative that does what I need a red dot to do, for the activities I do without breaking the bank.
Personally, I don't need a mil-spec optic as long as the site is durable and holds zero. If I find myself in a real combat situation where I need everything my Aimpoint or Eotech is capable of withstanding, the world is doomed and all hell must have broken loose.
