TCL D1 Fingerprint Smart Lock review: More than the basics

This inexpensive smart lock covers the basics--and even provides a fingerprint reader--making for a very affordable smart lock if you don't need any other bells and whistles. You probably know TCL for its TVs, soundbars, and smart appliances more than its home security devices, but the manufacturer now offers no fewer than six smart locks (and one home security camera, too). One of its most ambitious smart locks--the D1 Pro Palm Vein Smart Lock--was a better value than the even more ambitious TCL D1 Max 3-in-1 Video Smart Lock, which boasted an integrated video doorbell. Both of those devices had their flaws, but if you're willing to give up palm vein scanning technology and an integrated camera to see your visitors, the far more basic TCL D1 is the better value. This less-expensive alternative retains the PIN pad, fingerprint scanner, and Wi-Fi connectivity in a package that's available at Amazon for just 90.
