Very pleased and Highly Recommended! Arrived fairly well packaged in bubble wrap. Purchased the small board pair for trainings. Board quality seems good. Build idea with the edged bottom does keep the board from moving on grass. There can be some slight movement if it's not dug in completely but very minimal to non noticeable. The only time I could really tell if it moved was when I'd put together both boards next to each other to create a longer board. Other than that the board stays in place as expected without the use of a sandbag or any additional assistance. If you're really trying to make sure it doesn't move you could use something to do so but doesn't seem necessary in my opinion. Board is responsive. Ball comes off the board in the direction you would expect. Force to board can be soft but there's less bounce back but with a firm pass it will respond as expected. Harder passes will definitely result in a stronger return. In short, if you play around with the board a bit you can tell how the board will respond. If soft passes are a training idea, then the adjustment you'll need to make is being within a few steps of the board, but very possible to do a lot of variations. The edged bottom on the board was the biggest selling point for me so I didn't have to bring extra equipment to hold it down. FYI I use the boards on firm ground and cannot comment on other surfaces because I have not experienced them with the boards. Overall pleased and would recommend. Pricing is very competitive compared to other board companies that offer the same product. Compared to other rebounders I wanted a board that offered durability and would last compared to the other rebounders made with material that could rip or lose responsiveness because fabric materials breakdown. Also very happy to support a US made company.
