We traveled from Rotherham to get these guys to fit some reversing sensors to my wife’s car, I’d been before and they were very professional for both alarms and a radio on my van and this time as before they were brilliant. The work was completed ahead of time and one of the guys came out and spent 10 minutes explaining EXACTLY how parking sensors worked which was great as I hadn’t a clue. We are very pleased with both the professionalism of the people and the work in which they do. Perfect!!! Many, many thanks for such a great company.

Was there today, 18th May at 8am to have the front components on my ford focus changed to a pair of Audison Prima’s, along with some sound deadening anf wave diffusers fitted.
Got there and the staff couldnt have been more helpful or polite. Told me it would he ready by midday. After 2 and half hrs i went to have a look to see how the work was going and the technicians were almost done with it even talking to me during finishing off the install to advise me on future upgrades im thinking of and how to achieve the result im after.
Overall im very impressed, can’t reccommend them enough and im definitely going back for the rear speakers and headunit, amp subwoofer setup in a few months.
They even vaccumed the car after they had finished and went through the setip of my current stock stereo to maoe sure the new speakers were set right, advising me on how to adjust the headunit to ensure optimal burn in for the new speakers.
