Excellent Product
Wow, just an excellent product that is well designed, well made, easy to use and super effective. The price is right too. Intuitive design means it is immediately obvious how to use and putting the jam in place takes seconds. Tested it out, and without putting so much force I risk damaging the door or surround, the door doesn’t budge. Renting a flat and have no clue how many keys are out there from former tenants - immediate security and peace of mind. Removes in a flash so no safety worries there either. Excellent and have bought another to gift to my daughter.

Handy security to have
Very easy to install and works on a large variety of door types. Latches do not matter with this. It's very sturdy when installed and will provide resistance for intruders. Packs away nicely into a suitcase or handbag.

Good product!
Good product. Both my partner and I have used this when staying at hotels. Easy to use and seems to be effective. Plenty of other hotel door security products don't really work, or are hit and miss with which doors they work on, but so far this has been good everywhere.

get it
really works, Initially I was struggling to set it up but once i got the hang of what way to turn it this thing has been a godsend. Worth it for piece of mind for just one night, priceless for many. It really is a solid fit as well, nothing is going to open the door once it is installed. Useful as traveling and have had a person come in using their keycard recently...

Not convinced it works
I think if someone wanted to break in they can easily push this open especially if carpet flooring. But quality was alright and sort of does rhe job

Safe and secure.
This is great. It's very easy to use, and I literally couldn't open the door once it was in place. It makes me feel safe knowing that it's there. Thank you.

When I opened the box I could not believe the size of this item. I was not sure if it was going to give me piece of mind I expected. After testing it I was so pleased that this little item can be so effective. Noone is going to get through my front door unless they bust my door down. It is 100% effective and I am so glad I found this item. I really really recommend this and it is portable for travel. You will have guaranteed peace of mind.

Si quieres abrir una puerta con esto puesto... Tienes que romper la puerta entera. Era muy escéptico con este producto, pero realmente cumple muy bien. Lo pongo cuando no quiero distracciones en casa y necesito concentración

Perfect for safety for solo women travellers. Insert this and feel safe, whenever u are travelling alone, especially in hotel rooms that don’t have additional chain locks.
