Problem I see is abuse and loss of product...idk about you guys, but I see the way people treat rentals...I wouldn't want to let someone I don't personally know within 10ft of my computer unsupervised... But let's say someone damages your computer... How you gonna get money out of them to repair... Let's say they just never send it back... I believe dive shops haveihave that they can claim against if something happens... You're just sol... You can say they have to have an account here... But that's not hard... Say they have to have x number of posts... Also not hard to manage... But then I also tend to not trust people...
