It was very easy to fit esp. with 2 diff sized screws to choose from based on our door frame arrangements. Seems very secure. We feel safe now with our infant. Thank you for delivering before time.

This product is a fire hazard and an egress entrapment.

Reviewed in the United States on 29 May 2019

Colour Name: Brushed ChromeVerified Purchase

This lock is a fire hazard. The cheap Chinese aluminum milling makes it difficult to unlock. The spring mechanism and aluminum will hang up in the locked position. I would not purchase this product. My return window has passed so I guess I’m stuck with this piece of junk. Unfortunately it was mortised into the wood frame so once removed there is a huge chunk of wood missing on the door frame. Save your money... beware. You can be trapped inside in an emergency. Buy another product!! Good luck if you don’t read this review.

Amazon shouldn’t allow this product to be sold. It is a huge liability.

Economical but strong and easy to install --- keep it simple!

Reviewed in the United States on 3 February 2021

Colour Name: Polished BrassVerified Purchase

This arrangement worked the best for me because I have a pushbutton deadbolt lock that has case that is 7/8 inch deep, and flip locks made for ordinary (round shaped) deadbolts simply won't work for my situation. Since this doesn't mount on top of a deadbolt turn handle like a flip lock, this was the ultimate solution for me. This was less money that a flip lock, and the irony is that if someone does successfully pick or bump my electronic deadbolt, I will know that someone attempted, and they still won't be able to get in. I needed to do a little mortise work with a chisel to recess the mounting plate a bit, but I'm pretty handy and have done that sort of thing before. Overall, the mounting was super easy and pretty fast. It's nice to know that this can withstand an amazing 800 pounds of resistance, which is a great partner for my metal door. And of course the bright brass finish matched the rest of my hardware very nicely. Thank you.

False Security - A Pointless Exercise

Reviewed in the United States on 9 June 2020

Colour Name: Brushed ChromeVerified Purchase

The screws provided are so soft they fail DURING INSTALLATION! Look at the picture! That is what happens when you try to screw this into a 2 x 4 stud - - complete failure. The screws are far too soft to withstand the torque needed to get them into your studs.

In fact, the entire device is made of this same ultra soft, ultra cheap steel. This product is "eyewash" or "eye candy" for those who want security, but have no expertise. It is so cheaply made it is not worth the time and bother to install it. Yes, they fooled me. But ONLY ONCE!

I bought two, and they are being returned immediately as rubbish!

Lucky I didn't have to call the fire department to break the door down.

Reviewed in the United States on 7 June 2020

Colour Name: Brushed ChromeVerified Purchase

Bought one (balcony door) and it worked great so I bought another. The 2nd one would lock and unlock until I mounted it. I put the one smaller screw in and tried it out before putting the three longer screws in. It no longer would unlock so I was basically stuck in my apartment. Luckily I had only put the small screw in and could rip it out after a good amount of work. If I had put the three screws in I probably would've had to call the fire department to come and break the door down. Find a different option

The wood screws are HORRIBLE!

Reviewed in the United States on 10 June 2020

Colour Name: Brushed ChromeVerified Purchase

For the install I had to chip away into the door and all looked fine. The is that the heads of 2 out of the 3 long wood screws broke off. I couldnt back out the screw was lodged into the wood. I cant reuse the hole to drive in another screw. So i have to patchup the area I chipped away. Such a paint in the butt install. They need to supply strong wood screws.
