I've gone through a few 3-wheel push carts over the years, started with a ClicGear, then a Sun Mountain, and now a CaddyTek.
I would say out of the 3 the ClicGear was my least favorite, had to replace two aluminum struts that attach to the rear wheels that snapped while I was out playing, replaced worn out tires (normal maintenance), although the front tire has a tracking adjustment it never seemed to track straight.
The Sun Mountain was good but has a terrible brake design, the brake cable is under stress when disengaged and will eventually break, more than once in my case.
Purchased the CaddyTek EZ V8 back in January and probably my favorite so far but haven't had it long enough to see how well it will hold up. Rolls nice, seems sturdy, and has the best storage.
Looks like the prices have really shot up, I paid $156 for the CaddyTek (open box from Amazon) 6 months ago and a new one is now listed in the $300 range. Costco was carrying a slightly different CaddyTek model for $150 but not sure if they still have it.
