"The FloDrain sections clip together very easily and stay held together. Cutting a hole at the correct position was very quick and easy using the moulded guides. My only gripe was that one end piece simply clips in but the other needs to be glued in place. Obvious when you think about it, but it meant that I had to go looking for the plastic glue. The top covers clip on perfectly and firmly and yet are quick to release. Tip: Use masking tape over the covers when cementing in place to avoid any marks."
