The malfunction speed for the Zowie implemented 3310 (30g) and general 3360 (50g) are both humanly impossible as well as the frame data differing the two sensors outside of their comfortable DPI ranges (20 frames or 4ms of smoothing on all DPI steps for 3310 | 2 frames of smoothing 0.2ms of smoothing ≤2000 DPI for 3360) is also only noticeable by computer testing. The 3310 implementation from Zowie today has no issues with the tilt slam issue, which the 3360 DOES NOT have already. The two sensors barely differ pretty much.
The only thing that might be worth waiting when it comes to the Next Gen Zowie FKs is that they upgrade their switches to Omron and they fix their prominent cheap feeling mouse wheels.
