We have this flower box together with trellis ordered over a year ago and it's true, the box looks nice and is also very easy to assemble by locking.
After over a year of plastic does not look very presentable and also has places spots that not even can be removed with plastic cleaner. The course looks not very pretty. The box is for a planting absolutely no longer mobile, shifting to another location immediately leads to the fact that solving the connectors. I also recommend before planting for whatsoever drainage facility to provide, in order to avoid waterlogging.
The 3 star I forgive but because you obviously have to consider the price-performance ratio. I can not expect miracles in such a price. So if you have a protected place where the trellis stands and no longer needs to be moved a millimeter, for this may actually be a good solution. We are now to look for a solution wertigeren and are no longer to convince of plastic products in the field.
