It's the fourth bike I have the Box setup on and it's been working great. The install and setup is straightforward as the other existing systems. The shifting feel at the paddle is somewhat unique like a hybrid feel of both the Shimano and SRAM just in a single paddle. Took me less than a few miles to get used to it- really intuitive. Vital on their review last month highlighted incompatibility with the E13's 9t cog but I do not have this problem as two of my bikes (both recent Bike of the Day btw..lol) have the same identical Box system mated to the TRSr cassette. Fine tuning the B tension and the proper just right chain length was the key factor for me in mating the two systems. Nonetheless, I like the Box system bec it looks dope and it has that feel-good feeling that we all have another option beyond the two current obvious offerings.
