Got my son out of a tight spot when he broke his car key. He popped in and they cut a new one at a very reasonable price and got him back on the road. Thanks, another teenager on the road .

Custom cut 4 200x100mm laminate panes for a bespoke inset shower shelf, 2 smoked and 2 frosted. All cut perfectly but I gave them the wrong measurements accidentally, took back and it was absolutely no trouble for them to amend them the same day.
Granted its a bit hit and miss when theyre open but I cant fault the service I received and by far the best price I could find.
