Review: Liver savers! - These have been a life saver to our front and back doors now that our 4 year olds have established how to open our arms reach safety locks and can unlock those. These are super sturdy, fairly heavy, easy to install and maneuver. We purchased the black ones to go with the rest of our hardware. They can fit/ adjust to any door frame.
Review: Added level of safety for Peace of Mind! - Added level of safety for Peace of Mind ! I have patio doors leading to the backyard and pool and have grandkids around a lot . We have lever type door handles with regular locks and even alarm sensors on those doors but these locks provide another level of safety and peace of mind. We installed at the top of the door so no chance little ones can get to it and figure out how to unlock. Easy to install, functional and are not an eye sore at all. Great product!!

### ⭐⭐⭐⭐⭐ Highly secure and easy to install
*by N***Y on October 23, 2024*

I recently purchased the Steinwhale 4Pack Home Security Door Latches, and I am thoroughly impressed. These latches offer a solid sense of security for my home, with a heavy-duty design that feels incredibly sturdy. The build quality is excellent, made from durable materials that give me confidence in their longevity. Installation was a breeze. Each latch came with all the necessary hardware, and the instructions were straightforward. I had all four latches installed in less than 30 minutes with just a few basic tools. The sleek and low-profile design is perfect—it blends seamlessly with my doors without being an eyesore. One of the standout features is how effective they are in preventing forced entry. Once engaged, the latch keeps the door firmly secured, providing an additional layer of security beyond a standard lock or deadbolt. It’s great peace of mind, especially for anyone who wants extra security for their home or apartment. Overall, the Steinwhale latches are an excellent investment. The value you get with the 4-pack is unbeatable, and I would highly recommend these to anyone looking for easy-to-install, high-quality home
