I bought a refurbished clicker 3.5 cart 2 weeks ago from clicker. Paid less then 150.00 shipped to my door. Have used it twice so far.
Goes up and down hills with ease,brake works well on hills. Yesterday walked a very hilly course and hand to use the hand brake going down a winding cart path to help slow the cart down.
Will see how well umbrella holder works next week when my 68 inch Cobra umbrella come in.
Cart is very well made, folds up easy and does not take up a lot of room. I also freeze my water bottles and punt into my bag and take out as needed. Drink holder works well. There are many places one can add drink holders or other items on the cart.
Might try to add a insulated fordable lunch bag to the cart if I need more space for sandwich. Walking instead of riding in a cart is great exercise and I too find a lot of golf balls that others in carts drive buy.
If you are looking for a cart you can't go wrong with a clickgear.
Will update after umbrella arrives.
