Just bought several beams of this product. I wouldn't say the quality is exceptional but it is usable. I bought longer than I need so I could trim where required. I'm happy I did so as several of the boards came with damage to the ends. One of them had been planed almost 2 cms more than advertised. (thickness 34.6mms rather than 38mm) And that was a slice that prolonged into the board for 200mm. 2 other boards came not planed on one side and 1 board has gash of missing wood on one end almost 100mm in length 20mm wide and 30 mm deep. Not a problem for me as I bought them long enough to be trimmed into the desired length but I could see how this would affect some buyers. Delivery was fast and perfect. I'm giving 4 stars as the boards are good enough but not perfect as described and for someone who buys exact measurements would then cause trouble. Hopefully this review will educate some to buy a bit longer and trim.
