I gave it 4 stars because it was mostly a positive experience, but the few cons made it 4 vs. 5 for me.Pros:Pretty easy to assemble. Manual was decent for something like this. Use a proper 10mm socket vs. using the wrench they give you. I was careful to not overtighten - the tube metal they're using I don't think can take much in the way of torque before it buckles.Fairly heavy base so it does stay along the ground when pushing. It doesn't fly up. That's a good thing.Pre-lubricated bearings (and it would seem to be true, because it rolls pretty smoothly). I did like that they included some maintenance in the manual, including when (how often) to lube this going forward and how to do so by removing the wheel's hubcap cover to apply grease.I was able to pick up pine-needles that were embedded in the grass a lot better than I expected - I did have to use the lowest setting to be effective. For larger leaves, I put it one notch higher on the depth and picked up a bunch of oak leaves. See photos.I was also able to get dead grass from mowing up and collected for use in the chicken coop. This is easier than having to rake it.You do have to watch out for vegetation getting caught around the wheels on the edges. Easy enough to remove/unwind but if you feel resistance that might be why. The hopper is fairly big, but depending on what you're collecting, you have to empty it relatively often because the debris will start falling back into the sweepers if you overfill it.Cons:I think this is a bit overpriced for what it offers. They did drop the price from when I received it (~$90 down to ~$80).It's just some tube metal held together by some M6 bolts, so not sure how durable it'll be long-term.The depth adjust is a simple hand-tightening nut, but sliding it up and down is a but cumbersome.It's a bit short for use by a taller person (over 6'), but many lawnmower sized implements are like this. It's usable, but not ideal in terms of height.
