Doubled my range on the trails
Swapped the stock stubby antenna for this 19-inch whip on my TrailBlazer 500 and the difference is night and day. Reaching folks three canyons over that used to be dead air. The waterproof whip has survived two mud runs and a car wash with zero issues. Worth every penny at the sale price.

Big improvement, watch your garage
Solid range boost on my TrailBlazer 250. Just remember it's 19 inches tall — I've clipped it twice on the garage door. That's on me, not the antenna.

Magnet mount lost grip on highway
Range was excellent while it worked, but the magnetic base let go at 65 mph on the interstate and the antenna went flying. Cable and whip seem fine, so maybe my roof coating was the problem, but I can't recommend it for highway use.
