The first qualifier is that I installed this on a commercial metal door. If it was a high traffic area I wouldn't have, but since it doesn't get used as much as a residential door I think it's a good choice. The installation, while ultimately easy, was difficult because the instructions were a poor Chinese translation and were confusing. I had to look up YouTube videos to figure it out. Aside from that, installation was a snap. The construction is solid and good, and once you've configured the app the lock works well with the app giving you notifications whenever it's unlocked by a fingerprint or fob or keypad. NOTE: I had to return my original purchase because the fingerprint ID stopped working after a few days. But it was also after 3 days of hard rain, and as I mentioned I installed this on a metal door with no storm door protection. The lock has sealing gaskets but I suspect the moisture was just too much. Amazon replaced it easily, and when I reinstalled the lock I added a bead of waterproof silicon around the seal. Since then it has performed perfectly. I'm happy with my choice of purchase and the features of the lock which suited my needs perfectly.

This device works converting a VGA output to HDMI. The quality is very good.

I was hoping to get around an issue with ubuntu when no sound coming through hdmi. This didnt solve the issue but picture was good and it works as described. I had to unplug sound then re-plug after boot up to get sound. So OS issue not a product issue.

Great for placing on a music stand during performance

Plug and play, does what it needs to do. No complaints!

Well made light with high and low settings. Exactly what I was looking for. Sturdy clip very nice light.

Works as expected. Very easy to install. Happy with the purchase.

Honestly,it works well,I bought another lock from their store, and use the same one app,It is so convenient,the fingerprint unlocking is quick,and you can use 3 other different way to unlock/lock the door,Key,Password,Ic card.
