The flexibility is so very very useable. With this light you don't need anyone to hold the a flashlight. Also you can actually keep your mouth close by buying one of these. I know a lot of people have held a mini mag light or something similar in there mouth to see. I've had to do it myself. But seriously guys, if you already have just at least 1 dewalt tool that uses the same battery. Then I would defiantly purchase one of these. It's well worth the money. So far I have never had to change the bulb, I believe it's because the flexible arm takes the jolt, instead of the head. Enjoy your Dewalt light. You will be very pleased.
