Good quality, precision cut and well packaged for safe shipment.

Initially we ordered one acrylic prismatic light diffuser, measured and cut to size because my Dad had an accident with our old one where it broke in half! We was absolutely so impressed and satisfied with your service and products that we then ordered another one straight away, and this certainly did not disappoint either. We would not hesitate whatsoever in recommending your fantastic company. Thank you, from The Wilsons

A replacement for a light unit on a kitchen extractor hood. It works perfectly and because it is lighter than the original it is easily and invisibly affixed with velcro.

Good service all round light diffusers have made a big difference as the old ones were badly discoloured.

Used these acrylic prismatic light diffusers to replace old and broken lighting panels in the kitchen. Excellent product, exactly what was required, and all panels cut to our exact specifications which made fitting them so much easier. Received well packaged and intact. Would have given Simply Plastics a 5* rating if communication about delivery had been better. Actually had to ‘phone them twice to check when delivery could be expected as website said within 2 to 3 days. Was advised it was within 3 to 5 days. Delivery was actually 6 working days. I would still recommend using Simply Plastics.

to replace a ceiling tile in my kitchen. excellent service & very good quality. no faults to complain of .

Great service well packed and protected will definitely use again acrylic prismatic light diffuser.

The light diffuser worked really well at softening the harsh bare light in my kitchen. It was perfectly cut to size by Simply Plastics and the price was highly competitive and these would normally cost twice the price. We had it fitted quite easily, note to use a blunt drill at lower speed so as not to crack any drill holes made. Recommended.

Used it to replace a diffuser in the lift at a residential home. Worked a treat and improved light transfer

Fabulous product and exceptional service. Lightning fast delivery. Fantastic follow-up and packaging.

Very nice diffuser plastic (acrylic) cut to size by SimplyPlastics which saves a lot of time. Most other companies will just sell you a standard sized sheet. Delivery was excellent via courier with protective cardboard backing cards. I would deal with this company again if ever required.
