Works so well. added security is always worth the money

Easy to install, very sturdy and good quality

Ideal product to add security to patio doors etc when you are absent from home, real easy to fit.

Nicely made solid sash jammers , good value for money £9.99 for 8 , it's surprising how many you use so more is always better (4 per single door) and 2 per window opening (8 per pair of french doors - 4 each door ).Quickly dispatched thanks to Amazon Prime nicely boxed securely and supplied with screws for fitting .I was sceptical as to how much difference these little sash jammers would make to an average window or door , but on fitting them , I am impressed and glad that I did and I bought 2 sets of 8 (16 total) for £20.00 and feel that that was very good value for money for the amount of additional security they provide . These sash jammers are good "additional" security only you should still ensure you have insurance approved locks on your doors etc in the first place and use these to enhance rather than replace or substitute good primary locks on your doors and windows .Buy them well worth the money and small effort to install.VERY basic DIY ability requiredTools needed1 x phillips head screw driver ( also known as a crosshead)1 x power drill1 x 3 mm drill bit (standard HSS ) steel cutting NOT masonarytime to fit 4 per door ......5 mintime to fit 2 per window 3minshope this helps !

Don't expect to see "swiss" quality product, but it seems okaish more for prevention reasons. What I mean is - if somebody will try to force their way a litter more - this things won't resist, unless you place many of them on whole perimeter.What disappointed me are the screws - that directly compromise the security point (main one for this product). First of all - they are short and out of the whole length, there is less then 10 mm effective screw going into wood/plastic. Although screws look nice - I've got two of them broken (head fly off) and this is by using a manual screwdriver and without forcing and even finishing to get the screw in.In the end - used some of my own screws.Guys - don't save on this little bits, they are ruining the whole experience and compromising security.

Liked the product, but packers should fit a lot better. Very fidley to hold both jammer and packer wile fitting.

We have a hatch into eaves storage in the spare room. Having a hinged door here is impractical as it would impact too much on the use of the room. I repurposed 6 of these to hold this hatch and allow its complete removal. They work exceptionally well for this purpose and the hatch doesnt budge at all when held in place. There is a satisfying click when they are spun into place and are robust enough to hold the hatch close to the wall with it resting on the main section.

They are good value for ur money frel much safer now
