Overall, great product, could just use some small tweaks to make it better, but still a 5 star for me.Out the box, it was just a box and bag of parts. Not terribly labeled, but definitely not crystal clear. The instructions are so dark, it makes it a little hard to see what direction everything is supposed to go in. The 'rubber' edging on the shovel itself, I have no idea if I installed that right at all. The instructions are vague, and the parts themselves can be adjusted but it does not tell you why you should or would need to do this. I 'guessed' to keep them as least exposed and 'thought' this would be adjusted as wear and tear occurs over time. The way the wheel clamps go on is a joke and not clear at all. I clearly installed them the way I have used other clamp/pins like this yet clearly that was wrong as one completely just fell off. I rigged it up on my own with some other parts I had. That said, the wheels appear to have gaskets to fill with air if they get low. Guessing they have an inner tube, not that it said within the instructions either. Although the flexibility of the adjustability is great, it is a touch cumbersome to do if you are literally in the snow at the time. Undoing a wing nut and such is not the easiest to do with cold hands, let alone gloved ones.However, it does do an incredible job! I originally got this as my home had a LONG concrete driveway that took forever to shovel by hand. Since then, I moved and now have an even longer gravel driveway. Fun fact, this actually will work on one. Since you can control the angle and depth this goes down to, you can basically skim the top just above the gravel and still clear away the bulk of the snow to be able to get to the street. Since my driveway is also now at an incline, the wheels are a dream and back saver! The ability to change the angle and direction are incredible, especially since some of us are short and typically have issues with items like this.Overall, for the price this is a great deal. Could use a few small tweaks to make it better if they wanted though.
