• Great Digital Lock at a bargain price!
  Believe or not, I received the lock today and installed it. It worked better than I thought! Well made, looks great too. I just ordered the second one today. I did not need to do anything on my door, just replaced the handle, fix holes for normal door handle. This is a great advantages. I had a digital look from Homedepot for $100 but I had to re-draw a bigger hole on the door to fit the look which was too much work. The installation for this one is so easy.. Highly recommended.
  

• Great for an office
  I bought this for my small business. We've had some turnover over the last few months, and was tired of re-keying the locks every time (expensive even when you DIY). So I tried this a few days ago and it's great. The only drawback I've found is speed, you have to be relatively quick on the draw to type in the code then turn handle (probably 3 seconds). Not sure about the battery backup deal, would be nice to have a real key, but if you replace batteries it shouldn't be an issue

• Excellent number lock
  Lock works good. I wish it had an override mechanism or a switch so that it locks only when required. The lock quality is OK.
