Lenz security came to fit an alarm system for my Mother-In-Law. They told me what to expect prior to visiting, in terms of time required, costs, aftercare and generally anything to expect during the visit. They turned up on time despite having to travel fairly far and were courteous and professional throughout, being sure to ask us before doing any alterations, such as moving furniture before drilling holes and after fitting and testing. They thoroughly explained the setup and how to use it and even my technophobe Mum-in-Law (who has never even used email) grasped it after they went through it all and demonstrated. I would highly recommend Lenz Security.
