They gave communicative, attentive and prompt service
Quick service and the best gaffer tape in the business. Thanks
Website is easy to navigate although information on the products could be improved. Other than this the order arrived very quickly.
Purchase experience was fine, delivery time was a bit on the slow side taking 7 days to arrive. Otherwise all ok, product is fine.

Easy to order, item arrived quickly
I am impressed with the easy ability to order asbestos protection equipment and that the website also suggests other items to consider, however one item on my order was incorrectly sent which did cause us a problem at the time of use. (ordered a double bag set and was only sent a single bag set)
I received an Excellent fast service no hassle at all
Service provided was good although courier couldn't find our site and so dropped off at nearby school which we weren't told about until I made contact
Item was urgent requirement and guaranteed next day delivery - received three days later
