The troughs are very good - sturdy, visually appealing and probably long-lasting. The only downside is that there are no drainage holes, although the hole positions are molded on the bottom. A couple of minutes with a drill solves that issue quite easily.
I bought this as I needed an exact replacement for a broken one and couldn't find it in local shops.
It's sturdy ,(except when dropped from a 2nd floor window sill).
