Tried a few over the years and actually prefer the Fleshlight since it can be used between pillows (hands free). Otherwise, sleeves still require the use of my hand (and lube of course) and I can just as easily use my foreskin. So... I would recommend a Fleshlight over a sleeve.

I've got a Super Head Honcho from Adam & Eve few months back and love the feel of it for some different. It's no sub for the real thing like a good old Bj or fucking from the wife but I do enjoy getting off with it. O do have let the wife use on me a week or so ago and she said haven't cum like I did for her like that in long time. ( about enough to fill a shot glass of cum) She want to play with on me now about once a week. Best way is to use it is to warm it up in hot water and lube up and have fun.
