This thing is nice. Easy to install, easy to set up, and looks fantastic. The only issue we've had is it chews through batteries like there's no tomorrow. I've only been using it for a month and I've changed batteries going g on my 3rd time. That gets expensive quickly. I don't know if I have a defective unit, but it's just me and my wife and we mainly go out the back door as our cars are parked in the garage. I would like to return it, but we're past our window. It would be nice if I could reach the manufacturer to either get an exchange or a refund as I believe there must be something wrong with it.Another thing is the hidden key access. There's no clear directions on how to remove the cover plate. I tried twisting the cap, pushing on it, etc. Then by way of dumb luck, I found out you gently push the dark cover at around the 5 o'clock position and the top of the disc pops out. It's held on magnetically.If the seller reaches out, I'll update my rating depending on my experience. I cannot in good faith recommend this lockset right now due to the battery issue. There are less expensive, better alternatives. I installed the Teeho on my back door and if I don't hear from Harfo, I'll just buy another Teeho. Fingers crossed....One of the screw hole capsules is loose, it just endlessly spins around, does not tighten or loosen. Neither of the keys work, so that features is useless. If the batteries die, I'll be locked out of my house.This is a very secure unit and will purchase another for my back door.The door lock looks very nice installed. The instructions are easily read for the install which is straightforward. My only complaint is that this thing eats batteries badly and requires 4 AA batteries every change. Batteries usually only last a couple of weeks before they get Uber low and require replacing.It seems to work fine. My problem is the picture for the silver set shows silver on the inside as well as the outside. This is not accurate. The battery cover over the deadbolt is black. I tried to email the seller directly & through Amazon but no response.Easy to program and do not need key. Much easier with ParinsonsEasy installation and looks great!It wasn't that easy to install on my door. I did manage to get it in only to have the door handle break about a week later. Quality is disappointing. The electronic door pad has been hit and miss. Sometimes it works sometimes it doesn't. I might have gotten a bad one but my suggestion is try another product.
