Awesone Master Lock bluetooth key safe

I already had a Master Lock key safe but upgraded it and bought the Bluetooth Key Safe 5441EURD - S, very easy to set up, very sturdy and heavy, and can give up to five personsl numbers out as well or open it from my iphone, it does everything it says it can and by far the best on the market, i do not have one negative thing to say about it

Be aware of the combination Master Lock

Purchased the round combination lock about a year ago for my tool cabinet. A few days ago I tried 4X's to open the lock & it would not open. I trusted this lock because it's been around for centuries. I have extremely important Tools in this cabinet and I had no idea what to do. This lock is not to be trusted and it is not reliable. I read the reviews on all their combination locks and they had absolutely no good reviews. I now have no idea how to get into this cabinet

No customer experience whatsoever

No customer experience whatsoever. Their padlocks are sold with a warranty, which is totally meaningless because the only way to make contact with them is via their online web form - I have done that 3 times over 3 weeks (uploading photos and including serial numbers as requested) and no one has contacted me. I telephoned their UK head office and there's no answer. Don't buy Master locks - buy Squires - they are really nice and helpful and immediately replaced a faulty padlock when I had to contact them.
