As stated previously, this one isn't designed for insertion which is a bit of a downside. However, as a clitoral stimulation vibrator, it does a nice job. It is not super powerful really, but it is strong enough to get the job done for me. For me, this isn't a great toy for a couple to play with together really, but it does do a nice job when the male wants to watch me play as well as keeping me sane when he isn't available.

The casing is smooth and otherwise unremarkable. The nubs on the top are rounded and smooth enough that even if you don't have the changeable tips handy it can be used, with nice stimulation from the nubs. A little more flexibility would be a nice touch, but this item isn't designed or marketed for that feature.

The small size is a big plus for this one. It can easily be tucked in a purse, under the bedside table, wherever you might want to stash it. The battery compartment opens a bit too easily for my tastes, it is fairly easy to turn it to "open" instead of "on". For my own personal tastes, I would not have objected to the tip being a little "softer" in shape, the edges of the circle of the tip feel almost as if they end abruptly. so I would have liked a little more slope. Changing the battery is another plus, very very simple to change out as needed.

Simple as can be to turn on the vibrator, just turn the base and the indicator on the side moves from off to on. As I stated before, it is not super powerful but it has enough strength behind it to do the job for me, though obviously results may vary. More than one speed would definitely make this a more useful item. I never cared for the tips, a couple of them felt too rough for use on my clit. It can be a bit noisier than I might have liked. No-one is going to hear you across the house, but it emits a definite buzzing that can be heard in the same room for sure. The battery usually lasts me quite a while even with regular use, and you can always tell when its running down as the normally adequate vibration becomes softer and weaker.

Depending on how wet you get, you may need to rinse and dry the tips or wipe the top of the vibrator. Other than that there is little to no maintenance required. I haven't used it with lube, but given the sturdy outside I would imagine it would be just fine to do so.
