Love this thing! I had just the right of power for a satisfactory night (or day!). The only thing I did not enjoy was how loud it could get. It might have been just me though. But does its job! Slim enough to be discreet when stored at home. You can easily change the vibration with one hand, just slide your hand up towards the nob and twist! When the batteries are brand new, you can bet that the vibrations will be fresh as it is 'hard'. You will notice if you turn it all the way up, and if the vibration is not a hard as it used to be, your battery life is dying. All you need to do is swap batteries! You really do not need lube, once you get going, your body will instantly 'lube' itself. ;P

Insertion can be done, but I do not recommend it. Others may feel different about that, but I, myself, am all about the thrusting or rubbing of the clit. Thats where I really enjoy it. My husband likes it even better when he does it for me. :)

For the price, it does not get any better than this. Very easy for you to travel with it. (Just put it in a see through zip loc baggy so that the employees of the airline don't accidentally grab it while searching your luggage ha ha ha!)

It also slips very easily in where ever you decide to store it. It is also very easy to clean since it is all plastic. I would recommend cleaning it immediately after use. I haven't used mine or a good few months and my battery rusted inside of it or something. But if I were to use it on a daily basis, I am sure that would have not happened.
