Reviews
What customers say
Customers praise the staff's skill and helpful service. A customer recalls Vasilii fixing a key-fob problem in a driveway in very cold weather, while separate accounts describe a small safe opened in under half an hour and a combination safe opened without damage, with its combination recovered. One customer reports that a key fob failed during programming, a cheaper one was supplied, and a request to order another OEM fob was declined.
