"Your company delivered the key next day."

Your company delivered the key next day, but I was rather surprised that the delivery driver did not know that he was delivering keys which are valuable security items. However all’s well that ends well – the keys fit the doors which is the main thing!

"My experience with this company has been very positive."

My experience with this company has been very positive. We ran into a couple of problems, and they were dealt with promptly and politely. The problems occurred due to my lack of knowledge by the way. This is now the company I would go to with anything lock related.

Very helpful. On the phone 5 minutes after ordering asking if both locks were for the same house and, if so, would I like one key to do both locks.

Order was easy and arrived quick. I ordered the wrong thing, return was easy. The company were really easy to deal with and very friendly. I returned an item and the day it arrived back with them they messaged to say they had issued a refund. Very impressed.

"The service was outstanding from first email to delivery."

I contacted via email with a query about replacing a specific handle for my bifolds. Dave emailed straight back and even called me to ensure it was correct. I ordered that afternoon and it arrived the next day, perfect fit. I don’t usually leave reviews but I felt the service was outstanding.

"I ordered a handle which was an unusual size."

I ordered a handle which was an unusual size. The very nice man called me to double check I’d selected the right one to save me having to return it if not. Great service and quick postage.
