The worst thing about it is that you are at the mercy of QC when you order one. The way to remedy this is to find a very picky dealer who is willing to inspect their inventory for quality. You will find pieces that cut very well, handle very well, and have surprisingly good fit-finish, but you will also find some disappointing pieces if you are unlucky.
The only real flaw I find in the product in general is the inability to readily remove the handle for maintenance and polishing. However, given the price point of these swords, repolishing or changing fittings and interior cleaning and such aren't really a major problem. For a little more, you can get those elements in the Practical Plus. However, for many people and their purposes, having a "permanent" handle may in fact be advantageous. Really up to you.
