WANLIAN 1PCS Door Window Lock Stopper Adjustable Thick Sliding Safety Anti Theft Children Security LockChild Plastic Steel Aluminium Rails Limit Window Door Anti Slip

Great bit of kit to feel more secure

Arrived promptly and works a treat. Good quality. Would buy again.

Great product, easy to install, easy to remove.Just pay attention of the doors are heavy and the speed you open them is high, the device may pop out.

Ok but didn't suit my door

Fantastic little lock does exactly what it says it does. Easy to fit and so strong my patio door does not open when this is on no matter how hard you try. Just so other purchases know righty tighty and lefty losey doesn't apply to this lock its the other way around but who cares when the price is good and the product is great.

I would not recommend this item. It did not work.

Door stop arrived today on time and it works perfectly and fits really well.

Bought as an additional security feature for holidays abroad, obviously had no chance to use them yet (#covid19sucks), however they are exactly what I wanted, they look easy to install, sturdy and well made so I have little doubt they will do the job.

Es sencillo de colocar. Se sienten buenos los materiales y resistentes en interiores

We used these on a cooler in a common public area. This really isn’t a lock, it can be removed with an hex wrench. It is useful in our situation because the cooler is used as a reserve for the main cooler. We want people to use the unlocked cooler first, then we reload it with warm soda for cooling and switch the lock over to keep people from getting warm sodas. It just keeps the door from sliding open, it’s not really a security lock with a key. It would also work anywhere it may be placed on the inside, like in a house, where the hex lock cannot be accessed. It can be tightened to the point where it doesn’t slip, doesn’t slide when adequately tightened. Solid product for the right situation.

Bought this for my mom who has my grandma that lives with her and is always trying to close the balcony door so when this is on she has no clue how to close the door on hot summer days definitely worth your money
