It's increasingly easy to find a decent wearable these days -- the real problem is deciding on the one that fits you the best -- perhaps literally. Now Lumoid, the startup best known for its short-term camera rental service, has got you covered. The company just added a new wearable section to its rental offerings (which also includes drones and other photography gear), allowing you to try out five different health trackers at home. Once you decide on something you like, you can order it from Lumoid's online store for a new unit and return the box of used gadgets. And if nothing strikes your fancy you just have to pay a $20 handling fee to ship them back.
