Ok, so I got this product in an attempt to get rid of massive loads of hair painlessly. This is my opinion based on my experience with it:
First impression, yes it works (very well, actually), but you must use a good amount in each area you want to remove hair. I tried a thin layer first, and got hardly anything off. In the end, I used about a whole bottle for one complete hair removal.
Another thing I've noticed is that a lot of people complain about the smell. Honestly, it's not that bad. If you've ever been in a hair salon, you've already experienced it, and while it's strong at first, you get used to it in under a minute (don't recommend having your mouth open though...)
After you've placed the stuff on, you're going to be waiting a while to get it off, so bring something to entertain yourself. Staring at the ceiling for 8-15 minutes is not an enjoyable practice for me. At the same time, however, PLEASE bring a timer in with you. Set it for 8 minutes, and try to wipe a small amount with a damp rag after it dings. If nothing comes off (or little does), try again after 9 minutes, 10 minutes, 11 minutes, etc. Point is DO NOT LEAVE IT ON PAST 15 MINUTES!!! If you do, YOU WILL GET CUT AND/OR BURNED!! (especially if you have placed it on rather sensitive areas). If you do leave it on though, and get hurt, don't worry, it only lasts for the rest of that day tops (it's a good idea to do this when you don't have anywhere to go), and while I'm on this subject, DO NOT place any kind of cream or anything to remove the burning sensation!!!! I did (stupidly) and it was like throwing a bunch of brush soaked in oil on the fire. I literally could not move for a good minute because it hurt so badly...
Something else I must stress is that you test it in a small area and wait at least a week before you go ahead and start going for the whole removal. I didn't do this, and while I was fine at first, 5-6 days later I got some really bad acne in the areas I applied this stuff. I bathe regularly, sometimes twice a day, and it only occurred in the areas I placed this stuff. Now this may just be some freakish reaction that only I will have to this stuff, but I do recommend testing it to see how it will affect you before you place it all over your body (don't be stupid like me).
One final remark is that it DOES NOT last 2 weeks. After 2-3 days I could noticeably see hair growing back in all the areas I had removed it from. Again, this may just be me, and maybe after multiple sessions it does get to this point, but based on my first experience I definitely think that the two week lapse that is advertised is a lie.
Hope this helps!
