## Customer Reviews

### ⭐⭐⭐ 







  
  
    key stuck in locks
  

*by L***A on Reviewed in the United Kingdom on 27 June 2017*

It's hard to write a review about these really because we ordered 9 but 4 out of the 9 when they was in locked position the key wouldn't come back out. that's not good so have returned the 4 and reordered another 4 hopefully these will be ok. they are heavy and seem strong enough it's not a problem with the key but it's the lock itself that's at fault. after being broke into while we was in the house I do feel like I need window locks.

### ⭐⭐⭐⭐⭐ 







  
  
    Good quality and does the job!
  

*by G***F on Reviewed in the United Kingdom on 23 March 2020*

Bought two of these to put each end of our conservatory door to increase security and also help pull door in as it was warped. A year later they are still working well and do exactly what we expected. Just ordered another one to replace the original lock on the conservatory window.

### ⭐⭐⭐⭐⭐ 







  
  
    A decent quality jammer
  

*by S***H on Reviewed in the United Kingdom on 26 September 2017*

A good, simple sash jammer. Seems reasonably well made and finish is good. The good thing is everything comes in the bag, the different screws and fixings, different spacers, different size contact pads etc. For the price I think these are a good choice for windows (might need something stronger for a door) and would buy more of the same if I needed similar.
