I installed this cage along with the canted flywheels and I immediately noticed an improvement in blaster accuracy and dart stability. I even noticed that I can hit something at 10 ft with elite darts, though I highly recommend not using elite darts. This cage does everything it promises for only 10 bucks.
For the price, a solid choice. I got one in a $5 upgrade kit along with worker 132's and worker Flywheels.
I was surprised with the combo. Certainly nothing wrong with this cage (Though, I with it had at least SOME guide tube)
