Bought the Whopper 140, and I'll be returning it. Normally, I would probably give a product like this a 2-star review instead of a 1-star because it actually picks up tennis balls just fine, but this product seems lazily designed and will definitely annoy you. The handles are held in by tension, and are a pain to get into position and seem to easily pop out whenever converting the hopper to the standing position. The rails on the side walls are the same width apart as the rails on the bottom, so when emptying the hopper, balls will get stuck in the sides. The lid is perpendicular to the handle arms, so if you want to open or close the lid while the arms are in the carry position, you need to open the arms to flip the lid. All three of these issues have very simple solutions (the handles prongs could be made closer together to increase tension, a mesh wall or angling/adding metal arms of the side wall so balls don't get stuck there, placing the lid perpendicular to the carry handles), so this was just lazy on Gamma's part.
