There are only two drawbacks to this product: 1. It is slightly too heavy when using a long screed. 2. The prop-up stand is not long enough, when using the prop, the motor can get concrete on it too easily. All in all, this is a very nice tool.

This makes flat work see like flat PLAY!

This product is wonderful, the only draw back is the Honda engine. The second time it was used it blew the throttle cable. Had to take it to an authorized Honda repair dealer. We live in the boonies, slowed the job down.
