Even though I didn't buy it, the service is excellent. Customer service is easily accessible and they're quick to issue refunds.

It is very useful.

After my work installed the system in the warehouse on several doors and more than a few years ago, I'm happy with it as a user; the days of cards or "smart" keys are over.

No more hassle with separate keys for our company

We are very happy with our decision to install Bold Smart Locks in our business premises. We weren't sure whether it would be possible with a double lock (at the top and in the middle of the door), but it was easily solved with two Smart Locks. No more hassle with separate keys, and we can decide when different people have access. We are very happy with this solution.
