Looking into the various locking mechanisms and lock types separately will go a long way in figuring out which restrictor is best for you.

Proster's 4-pack of cable window restrictors is slightly more expensive than Neotecks, but there is a good reason. To combat this, 3M double-sided tape allows you to apply restrictors for your children's younger years and easily remove them, leaving behind just a little glue residue.BeeGo Window Restrictors use the strongest 3M VHB tape to ensure and maintain a tough and robust fitting capable of withstanding a pulling weight of up to 30kg. Although its slimmed-down design is pleasing to the eye, it does increase the risk of the restrictor peeling off over time and under pressure. We love this 2-pack of code and cable window restrictors for their beefed-up 4-digits, which makes them much harder to crack.

It edges ahead of number nine with clearly labelled 3M tape, a 3-digit code lock and a slimmed-down, circular design. Working in conjunction with keys and codes, cables are great at promoting airflow while keeping the kids and pets safe. Similarly to number nine, this restrictor has a 20 cm steel cable, is plastic, and has a sleek black finish. Using the most powerful tape ensures our locks can withstand weight of up to 30kg (Approx weight of 6 year old child). The most enduring restrictors are built from heavy-duty stainless steel, which offers the strongest and safest window protection.

Self Adhesive: Each window lock contains industrial standard 3M VHB tape, meaning there is no need to drill or screw into your window frames and cause any visible damage.

Zinc alloy is a weaker and cheaper metal when compared to steel, which is why it's commonly used in the more budget-friendly restrictors. It might be unlikely, but children who have been eating their greens could really pull on it and potentially break the plastic by tugging the cable. Crafted with the industry leading 3M VHB tape, these window restrictors ensure a robust and enduring hold. The questionable aspect of Dreambaby's restrictor is that it's applied with included screws (which is good) but that it's also made of basic plastic.Knowing the kids are free to roam around the house safely is a feeling that only a parent can appreciate.

It's also made of a more durable and hardwearing plastic, and last but not least, its push-button opener is faff-free for adults but still makes it very hard for young children to crack. The downside is, as children begin to develop and get craftier, they could potentially learn how to open them!
