Review: Great product - Really does the job Highly recommend
Review: Omg! This safe is AWESOME! - This is by far the Best Safe! I have ever bought, it's easy to unpack, straight forward instructions, and has the battery compartment on the outside so if they run out, it's not a massive headache to replace them. But at the same time does not compromise the security of the safe! I bought the keyless one of this safe. And it's the best option, no more losing keys for it. Just input the number at the right height, no need to crawl on the floor to view the keypad any more. This is the best thing I have every bought. The drawers inside can be changed in order preferences which I loved, to maximise capacity. And feels solid built. Plus if its destroyed in a house fire. The company will give me a free replacement, once they have opened the old one! Which I thought was really nice of them, at a horrible time in your life a house fire! Yup very happy customer.

### ⭐ BUYER BEWARE
*by J***S on 12 October 2025*

On Monday, 15 September 2025 at 10:48 I sent the following email to Master Lock as I was concerned that the safe would not meet it's product description of being fireproof and or waterproof: "See blue arrows on 5 pictures, attached. There appears to be a manufacturing defect and I'm concerned these defects will affect the product's ability to remain water tight and fire resistant. I bought from your Master Lock Store on Amazon.co.uk. you can see on one picture where I can easily slide my finger nails into the gap in the seal/join. I look forward to hearing from you soon.!" I received an instant automated reply of my email and attachments (photos). I also instantly got an email confirming receipt and that they are "working to resolve" and gave a ticket number. I have heard nothing from Master Lock or their 'Future Brands Innovations' associate. On Saturday, 27 September 2025 at 22:35, I wrote: "Dear Sirs Further to my email with attached photographs that generated the below ticket number - 2 working weeks have passed without hearing anything from you. Please provide your response by return." At the time of writing (12.10.25) I have not heard anything from anyone as to my complaint. My Amazon order page only offers 2 options: [1] to get Master Lock Support - which leads me to the online form as above. And [2] to write a review. I hope that making public the absence of customer care and or any response will flush out a reply, failing which I will bring the matter to the attention of Amazon themselves. The product cost £338. I will endeavour to update in due course. UPDATE: 22.11.25 - despite emails and being issued a ticket number, I have heard NOTHING at all from Masterlock. I am furious. I'm left with a big, heavy, expensive product that is sold as fire and water proof, but has flaws in it's seams and no one to call or email, with no reasonable way to return it and not wanting to use it as faulty and needs replacing. Masterlock - your stonewalling is damaging your reputation, and I continue spreading the word about your non-existent customer service and faulty goods.
