XFORT Viper Key Locking Cable Window Restrictor in White, Durable Window Safety Lock for Child Safety and Window Security

Excellent and very easy to fit. Huge variety online so can be difficult to work out the best options but these have been superb. Makes me feel very safe with the little ones rooms. Easy to install and simple unlock when needed. Great price too

Brought these to go on the kids windows, really easy and simple to fit, sting sturdiness, looks perfectly fine, perfect value for money

This is a well made product with a plastic covered steel cable that should be strong enough to withstand any attempt to break it. It's dead easy to fix. However, I used my own screws as the screws that came with it were a bit too long and are intended to be impossible to unscrew. This is as a safety measure, although I don't imagine even the most intrepid child is up to unscrewing tightly fixed screws. One fact is that the plastic covers for the two parts you screw in are, once pushed over the metal parts, almost impossible to remove without breaking the covers. So again from a safety point of view it means children won't be up to that task either. But just make sure the two metal fixtures are screwed into exactly the right places before you push the covers over them. However, the positives well outweigh the slight negatives so don't let it put you off. I actually fixed two to each window, one on each side of the window, as an extra precaution as I was fitting these in high up windows for my grandson. I just wanted to be extra sure to keep him safe. There are cheaper types that look similar but the steel cable is thinner. Also, unlike the ones I'm reviewing here, some come with adhesive pads. NEVER use these, especially if securing a window that is high up and you have children. In my experience adhesive pads are simply not strong enough or are likely to just come off anyway, with what could be devastating results.

EXCELLENT . Easy to fit & makes the window a tad more secure. Good value & definately would buy again. Buying a pack for me mother to ramp up security & peace of mind .

The media could not be loaded. Value - the product, at the price I paid, was extremely good value. There were more affordable options available however there seemed to be a very obvious drop in quality and given their function I didn’t think this would be appropriate.Quality - the product appears to be of brilliant quality, more than enough for the average window. I’ve used a strong amount of force to open the window numerous times to test this, and no budging whatsoever.Installation - the instructions make it very simple, though the product itself is very intuitive and a common-sense approach can be applied. The first one took around 10 minutes, which included a little getting the feel for the product. The second took 5 minutes. There are 4 in the pack however I’m yet to install these.Appearance - the product looks high-quality, features nice covers for both screws. The product can’t be faulted on this in my opinion. There are various options dependent on the nature of the window in questionOverall - I couldn’t recommend this product highly enough. It’s functional, sturdy, easy to install fitting very well and will undoubtedly serve its purpose.

I recently bought these window restrictors for child safety, and I'm extremely pleased with the product. The quality is excellent; they feel robust and well-made, providing a real sense of security. Installation was surprisingly easy, even for someone like me who's not particularly handy. The restrictors came with clear instructions, and all the necessary hardware was included. Within minutes, I had them securely fitted, and now I have peace of mind knowing my children are safe around open windows. Highly recommended for any parent looking to enhance home safety.

Adds abit of extra safety (plus security), also when leaving full size window over night to let some cool air in after the heatwave we had.Would of liked cable to be thicker to help prevent scumbags trying to get in. But its better than nothing.Easy to fit...

The media could not be loaded. Absolutely brilliant. Look smart too
