Bests & Worsts Reviews from Amazon

Ok, let me preface this by saying: 1. I am a single mom 2. I have three rescued cats and two dogs running around at my feet 3. I have cancer 4. I just had surgery 3 days ago And 5. Today is the first day back to school for the kids amidst a pandemic By all accounts, today might have been the worst possible day to try to install this thing. But my Jr high student needs to be able to get in the house from her new school a half hour before I get home from the small business I run each day. So come hell or high water, I needed this thing installed by morning (I am not about to give her a key to lose). I can say without a doubt, this is the easiest thing I've done all year. It is easier than emptying the dishwasher. This thing practically installed itself. I was done in under 5 minutes. It was honestly shocking how quick and easy it was. It even detects by itself and switches to which direction of operation it needs. Ridic. I also changed the code in 10 seconds. I wish this was the first one I bought. It works flawlessly so far. We've tested it half a dozen times. I'll update if it doesn't hold up over time. So far, I highly recommend it.
