I saw the Clicgear 4.0 in a store this week. Clicgear was one of the frontrunners from my research online, but there was a supply problem at one time. I don't recall if that drove my decision.Curious if you compared to the Clicgear at the time while shopping as well? And if so, what was the deciding factor for the Sun Mountain that set it apart?
Clicgear's wheels and wheel base look larger than the VR1, or probably any other one I looked at. The frame too. It has an imposing structure.
The Clicgear has more storage than the VR1. I tend to not use the plastic storage case on the VR1. It seems too shallow to be very useful. I end up putting my extra balls, case for glasses, etc in the mesh bag. I'd rather have 2 small mesh bags, side by side, so I could separate stuff. (Exact opposite from purses where I don't want a bunch of compartments.)
The Clicgear has silicone belts that hold the bag in place. I don't care for those. It would require me to futz with 2 belts every time I put on or take off my bag. The VR1 has bungee cords with hooks. Each one takes about a second to hook/unhook.
The Clicgear weighs 21 pounds vs 18 for the VR1. As far as loading/unloading from the car, less weight is better. But -- the Clicgear folds up more compactly so it's like putting an almost square box in your car wrt the weight distribution. The VR1, folded up, is considerably longer. I can put it in the car with the wheels (heaviest end) going in last so I don't put extra strain on my back, but I'm still supporting 18 pounds while bent over at the waist. Or if I leave the brake off, I can put the wheels in first and roll it in. I'd rate the two carts about equal because Clicgear compensates for the extra weight by folding into a friendlier package.
Then the issue with the additional weight of the Clicgear is about pushing around an extra 16% of weight for the duration of your round.
I don't think you'd go wrong with either of these carts. If you're putting a cart and a golf bag into a car trunk, you may find an advantage to one over the other insofar as how well it fits with your golf bag.
