Wuben - fab design, quality and customer service.
I currently have 3 flashlights from Wuben; the X4 that I backed on Kickstarter, the F5 led panel, and now the E2 Pulse keychain light. The X4 is a fantastic powerhouse, the F5 is so useful and well designed. Wuben's customer service is outstanding - they sent me a redesigned switch for the X4 really quickly. Having tested the new E2 for almost a week now, it's earned a permanent place in my pocket and on my keychain. Really surprised about how well designed and built it is for such a tiny and light flashlight. However you use it or carry it you're not going to notice, until you need it So many functions in such a tiny, portable design (flashlight, side area light (with an additional heartbeat pulse), red/blue beacon, glow-in-the-dark case). It's like a micro X4 for your keychain/neck/bag! This looks like an essential EDC. The various functions are all just really useful for a thing that weighs effectively nothing and is so small. It has its limitations of course, out of necessity for its small form factor (the beam doesn't throw hundreds of meters and the battery doesn't last for days), but despite those compromises, it is genuinely useful.
