So after many days of research and review-reading, I think I have narrowed down my selection to two bullets - the RO-100mm soft tip v. high intensity bullet.
The thing I like about both bullets is that they are small, quiet, and discreet, as I live in a dorm and I have a very nosy roommate who miraculously "stumbles" upon things that I have hidden.
The major downside, I think, to the RO-100 is that it is only 3 vrooms. I'd upgrade to a different RO-mm, but that means moving up in size. Although I'm new to the toy world, I suspect that I must be pretty strong given that I have abused my family's handheld back-massager ( link ) since I was about 13.
The downside with the High Intensity Bullet, it seems, is that they break pretty easily - according to some of the reviews. Again, I'm a college student with just a $50 debit card to my name, so I can't replace a toy every month.
What are your thoughts?
