Quality is top notch. The wood is as advertised, durable, sturdy, color matched and fits together great. The box can be assembled in all of 5 minutes. The top is water-resistant as it is actually sealed and not slatted. Thus, it will not keep water out since the sides are slatted, but the bottom is wide open and allows water to drain without pooling.
Highly recommend for an outdoor storage box. One caveat, I would not use it as a seat, I do not think over time it would support adults sitting on it.
