Electric trolleys solve fatigue and create two new problems: they cost four figures, and they turn walking your ball into managing a machine. The E-BOOST is MGI's answer to golfers who want neither. It's a push cart in feel and footprint — you steer it, you're connected to it, it folds small — with a quiet brushless motor you engage at the press of a button when the ground goes uphill. On the flat you push as normal; on the climb to the 12th you let it pull. That's a genuinely well-judged middle ground, and for a lot of walkers it's the right one. It's a fraction of the price of a full remote caddy like the [Zip Navigator AT](product:mgi-zip-navigator-at), it's lighter to lift into a boot, and there's no remote to lose or learn. The honest limit is that it isn't a substitute for a remote trolley if what you actually want is to walk empty-handed — you're still steering, and on a genuinely mountainous course the assist is help rather than a solution. Buy it if hills are the problem and pushing isn't.
