    Super Secure and a Great Value
  

*by R***T on Reviewed in the United States on January 8, 2019*

This is a VERY SOLID lock! Everything about it is heavy-duty, including the keys. The deadbolt bar is made entirely of cut-proof hardened steel, not just a small steel insert in a softer bar. It's drill-proof, both places where drilling occurs, in the key slot and the mounting screws. It has a rotating collar so the lock can't be twisted and broken with a pipe wrench. It can't be bump-keyed either, at least not by your average criminal. The few who (allegedly) may be able to bump-key this lock won't be looking to steal my TV. They will be trying higher value targets. I feel VERY secure with this lock. Anyone who sees this lock is a Medeco will move on to another target. Installation was not difficult. Keeping the ball bearings in the screw holes while holding the lock on the door was challenging though lol. Medeco recommends Fluid Film lubricant ONLY, so pick this up at your local Lowes or at Amazon (Home Depot seems not to carry it): https://www.amazon.com/Lubricant-Corrosion-Inhibitor-11-75-oz/dp/B00PWZ0XNM/ref=sr_1_7?s=automotive&ie=UTF8&qid=1546957490&sr=1-7&keywords=Fluid+Film

    Really sturdy lock but hard to install
  

*by D***V on Reviewed in the United States on May 1, 2021*

It's really sturdy & solid lock - I believe if you are looking at Medeco you know all the benefits. Here are downsides:1. Read carefully lock dimensions & what door it would fit - locks are not adjustable2. Plan to spend $14+ for additional keys (but it's also a good one - you would ne able to duplicate keys without a Medeco card)3. If install an enforced break-plate be aware of your door frame restrictions (if constructed after 2010 no need to worry)4. Plan to have a spare key with someone who you trust in a case you lost keys - otherwise you could be in surprise for $250+ charge for drilling - solid still with hardened steel inserts - you will need Dremel grinder.Unless you are willing to go into $300+ category Medeco will be a choice.
