The spec I order was not in stock but was upgraded to the higher spec atmosphere extra charge. This was all agreed within hours of my order and it was even deliver within 24 hours. Excellent service and customer care by David Shakespeare. During installation I had no issue even though my driveway is on a bit of a slope. I even had alot of passersby asking about the product. So nidagravel may get a few orders from the Stirling area in the near future as a result!. Been driving in and out of the driveway for about 4/5 days and no issues except one skid but that was my fault as I had overfillied that area with gravel much higher than the recommended 20mm. Excellent product so far and would highly recommend.
