Well priced item delivered on time. good communication at all stages.
Easy to order and fast delivery
The Items ordered were sent promptly which was commendable, given the circumstances, (Covid pandemic 2020). Unfortunately the respirator and three filters I purchased were loosely placed within a box with no internal packaging, which led to the damage of one of the filters sealed bags, rendering the activated charcoal, which has an accelerated shelf life once exposed to the air, unfit for purpose. Other than that, great service.
As always, a great product and a swift service. Thanks again folks

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.
