I researched so many plyo boxes before deciding on this one. Othe products had reviewers complaining about how difficult assembly was, how directions weren’t clear and how pre-drilled holes didn’t line up. 1) this box arrived early which was a plus and 2) the quality of the wood and the craftsmanship was top notch – I feel like this should have been a much more expensive box! Directions were clear, pre-drilled holes lined up and they even included wood glue! Took only about 10 minutes to put together. I’m so impressed with this product and company, I would happily purchase from again.
