This is the first masturbator I've bought. The bottom line is it works really well. Not only does it produce a seriously hard erection, and a major climax with a lot of satisfying output, but I can real pleasure out of it before shooting which is psychologically important when I'm using it on my own. For instance by rotating the sleeve around my shaft instead of the usual up and down fisting I can get some wild sensations. Only downside is that when used with a lot of lubricant (which is needed to protect my foreskin join when pulling it on) it makes a very un-erotic slurping noise when I fist. Other practical benefits are that it is lightweight for travelling, and is a discrete color and appearance so it can be left in the shower or on a night table in a hotel. Also if the sleeve is over my head when I shoot it catches my cum, so no more snail trails on the sheets; and it can simply be washed inside out and left in the shower to dry. (I use a lubricant but no condoms with it for a better sensation, which also saves expense and disposal problems). Recommended!
