Window Locks, Aosite 2pcs Window Restrictor Child Safety Locks for UPVC, Window Safety Locks for Child Pets Safety, Self Adhesive, Adjustable Window Lock No Drilling for Metal, Wooden, Sliding Window

Good idea because you can adjust the length you want it open , sticks well to a clean surface , but you can use screwsOnly been up for a few days but seems ok , at the price it seems good value, definitely handy if you have cats and you don’t want them to get out but would like some air to circulate because you can adjust the gap using the chain, obviously it's not a security device and would not prevent anyone breaking in so don’t leave home with the window open unless you live high up, you get a pair

First of all they are easy to fit and very secure, easy to operate.. My slim cat was squeezing out the space at the window, I can keep my windows slightly open without her squeezing her little body out.. good value fir money ( two in a pack)

Easy to fit. Secure with sticky labels that were provided. Cat proof.

Seems really sturdy and great quality. Sticky pads also seem to hold well. Really easy to use and install.

Purchased these to stop my cat from escaping the house and getting onto a busy road. They are very well made, easy to install and do the job perfectly. I positioned them at the top of my window so that they are hidden by window blinds. I would highly recommend using these if you want to control the opening width of any window. Really pleased with my purchase.

Very happy with these. They were super easy to put on. I'm using them to keep a house cat in so didn't want to rely on the sticky backs, I us3d the screws and they were really easy. The screws provided could probably puncture the pvc themselves but I used a drill to do pilot holes for ease. It took about half an hour to fix four in place.They look smart and seem very secure. You can adjust how much you want to open the window using the chain, which you can't do with others.I will be ordering another 4 for the rest of the windows.

I bought these window limiters at the same time as I bought a similar device which uses a plastic bar instead of the chain. I thought it wise to try both kinds, as it's sometimes difficult to know which would be best. And this one, with the chain, works best, hands down. It's so easy to stick onto the window frame (although bear in mind that I have UPVC windows and the sticky stuff might not be so keen to stick onto wooden or painted frames). It's really easy to adjust the amount the window can open. And it's really easy to disengage if you want to open the window wide for a while, too.My only hesitation is that if you think a chain is going to be very secure you might be disappointed. This item is only as secure as the weakest part of it, and the little pin which goes through the chain is plastic and would probably not survive if it was yanked on quite hard. But it's more than secure enough to stop my lovely cats from getting out. They are rescue girls with no road sense at all, who had never been outside before they came to me so sadly I have to keep them in (for now at least--I'm hoping to get them a catio very soon!).Overall, then, a definite win.

Loved these easy to fit window holders, easy to fit and prevents my indoor cats getting out whilst letting fresh air in. So pleased I have ordered another set. Obviously for security reasons they can only be used when someone is home

Works really well.

Kann ich nur empfehlen. Halten was Sie besprechen . Würde ich jederzeit wieder kaufen.

Schnelle Lieferung, sieht aus wie beschrieben,macht was es soll

Es ist leicht anzubringen - ohne Bohren und tut was es soll. Haben es für unsere Katze gekauft, damit sie nicht sofort rausläuft, wenn wir mal kurz in den Garten müssen.
