Are you in the habit of leaving your umbrella behind at restaurants or in the car? You won't get a chance to forgot this one: it has a Bluetooth beacon built right in so you'll get an alert on your phone if you take off without it. The Davek Alert Umbrella is looking for support on Kickstarter, though as a well-established umbrella brand, it probably doesn't really need that $50,000 in order to bring it to market.
The Bluetooth unit is built into the base, and should last a couple years depending on use, at which point you can just replace it with a standard watch battery. The umbrella itself looks like a sturdy one, with a steel frame and push-button opening and closing action. Davek already prides itself on the strength of its umbrellas, and with the cheapest costing $49, one certainly hopes they'd take a beating.
You can pre-order an Alert Umbrella for $79 right now, which is cheaper than Davek's full-size "flagship" model, but if you wait for retail, you'll be paying $129. The price tag makes for one more reason you won't be leaving this one behind.
