    Bought 2 - Both Faulty
  

*by K***R on Reviewed in the United Kingdom on 1 September 2023*

I bought 2 of these and 1 had some pins fall out of it while still in the box.I should have seen this as a sign of the quality and returned both but I installed the second one - only for it to become faulty within weeks: The main barrel just spins and spins and won't lock.This also meant the lock wouldn't disengage to allow it to be removed.Luckily, after a removing the handles and a light few hammer taps it came out - but if not I'd have had an unlockable door along with an expensive call out to get it removed.I bought this for safety features and comparative price to the other brands - sticking to Yale from now on!

    Good Quality EuroCylinder/Thumbturn Lock
  

*by W***S on Reviewed in the United Kingdom on 11 April 2021*

This Eurocylinder with internal thumbturn lock replaced my unsafe double-cylinder lock on one of my fire exit doors. It was a direct replacement because I measured the old one first. It is working well and now provides safe, quick exit in case of fire. For security, outside doors with glass panels within reach of the interior thumbturn knob should not be used with this lock. If necessary, secure the door (no easy access panels!) rather than fitting double eurocylinder locks! I believe that this is a legal requirement for main fire exit doors for many residential premises now.

    DO NOT BUY THIS PRODUCT
  

*by S***Y on Reviewed in the United Kingdom on 19 October 2022*

I should have read the reviews! DO NOT BUY THIS PRODUCT. I purchased this lock and it only lasted 3 months! Thumb turn just spins and will not engage with the lock. Come on Amazon, stop ripping off your customers, take notice of these poor reviews.  You try and return a product more than 30 days old and is only sold by Amazon. I can't raise this with the supplier as no details are available, the Chat bot says look at the Warrantee repair policy, HTML link goes, oops sorry there is nothing here for your to read.
