This is a poor quality product, predominately made of pallet wood (some of which was split) and knocked together mostly with nails. I spent half a day strengthening and modifying it, then soaking it in creosote, (the wood lapped it up so was very dry). I couldn't recomend this product but didn't feel so strongly as to return and ask for a refund. On the plus side the shelf could be set at any desired height and the overall storage capacity is large.
