First time user and the experience was perfect.
Used their website to get a parts list download for a 2018 rupes rotary polisher after weeks of trying to find someone who could repair it , we found the required parts on the pdf list, and within 2 days of ordering, parts delivered, polisher now fixed for around £20!!
Highly recommend.

Many thanks!!!!

I came into the store after a Fein tool the colleagues behind the the counter were both helpful and knowledgeable.
I left them with what I needed and before the end of the day they had found what I needed and emailed everything I needed to do.
Superb service I would highly recommend.
