To start off, Tamatoys sucks.
I ordered
http://www.jlist.com/product/TMT399 and
http://www.jlist.com/product/TMT492 as my first two onaholes. I also got them from jlist which was another mistake. Nothing like wasting $50 on onaholes that break within 3 uses.
So now I ask, what are some good, durable onaholes? I'd like these to last a while. I don't need them to last forever, just… not to break almost immediately. What are your favorites?
