Lenovo launched a new smart clock at CES earlier this year, and it improved upon its previous models by giving it a pogo docking pin at the bottom and support for Amazon's Alexa. If you've been thinking of picking it up but haven't gotten the chance to until now, you may want to head over to the device's listing at Best Buy. Lenovo's Smart Clock Essential with Alexa is currently on sale for $45 on the retailer's website only for today -- there's less than 20 hours left for the deal as of this writing. The Smart Clock Essential with Alexa retains the brand's Smart Clock 2 cloth design. While its predecessors only supported Google Assistant, though, this model only supports the Alexa voice assistant.
