I have preferred threading to wax because sometimes my skin reacts to the wax.  I hate paying for either though but threading was hard to do on my own.  I am so glad I went ahead and bought this product.  I will say there is a learning curve.  It took a bit of time to learn how to make it work and even on the third and fourth go it took a second to get the right touch but it has become easier and easier with each use and it is effective when used right.  It also cost me the exact same as one lip threading would and I can use it over and over again.  I was a bit nervous it wouldn't work and a bit frustrated at the beginning but once I go the hang of it I am so glad I bought it.  I can't really comment on the razor, I haven't really used it, I bought this just for the threader and it was worth it.
