I have been vaping on my Joye 510 for almost a week now and I love the hell out of it. I have been seeing reviews on the DSE801 and I have been having this strong urge to get one. It looks cool even though it is a little bulky. Looks like it gets killer vapor too. I want one. Seems like a lot of online stores are out of stock though. Has this model become obsolete? Hope not.
