Looked them up. Honestly, for $15 what would one expect? Of course Ultrasabers is going to be better. Granted I knew that before I looked them up, but still, they weren't impressive at all.
I think you forgot the "1" in front of the "15".
I got their Dooku for a similar price, $115, and it is very nice. Perhaps the pic doesn't do their Obi justice. In most cases you get what you pay for and I feel I got my money's worth with my eFX Luke and Dooku.
In some cases, you get
MORE than your money's worth...
ULTRA SABERS!!!
Cheers!
