Question: What is the unit weight and relative size?
Document: I like the battery life and the brightness. The LED enables the long life so I'm ok with the color range of the strobe. The unit feels very well made. I have a feeling that if they wanted to, they could make this unit less than half the size, run it off a AAA battery and still exceed USCG regs. I really like the wire that helps you remove the two batteries, and the double O-ring feel.
No slide switch, just grab the head of the unit and twist...you can do this even if you're hands are shaking from exposure to cold water, and one handed if you've broken your other hand. Comes with an inflator clip and Velcro if you have a standard PFD.
When I fly my MTO Sport Autogyro on floats, I needed to have an inflatable device and the flashing strobe is a must to have beside it, so this unit is small and light to carry inside the lap of the surviving floating device.
Quality is A+  product is just the right size. When I ordered these I got exactly what I ordered..no surprises.
ones' life is priceless, this is a great dependable product, recommended to me by a uscg instructor. if you are out on the ocean, this item should be attached to your life jacket. should you fall overboard, it goes off automatically, and for its' size, it is extremely visible. highly recommend
Dumped it in a glass full of water with table salt added, activated immediately (I still cant figure where the sensor is but it is there). If the battery life was 8 hrs I'd be pissed about no absolute manual off but since the darn thing lasts 120 hrs, I just twist the unit on, then back off and it turns off the strobe. I know it's a little irritating but not a deal breaker with me, especially when the strobe keeps working more than ten times more expensive units.
Great quality product. I placed the strobe light in a pan of water after installing lithium batteries and, it started strobing. Seems like a very well made light and I love the small size, I have a self inflating vest and this fits underneath the velcro flap and you don't even know it's there. I would buy again! !
I purchased this strobe based on other positive reviews. It is a high quality construction, reported battery life is good, and the strobe is bright. As with almost all of these strobes, the size is just a little bulky. It does fit inside my Spinlock vest, but I wish it was a little smaller. I also couldn't figure out the clip for the inflation tube-ended up improvising the attachment. All-in-all, its a good light and serves its intended purpose.
great value and is just what i wanted. couldn't have asked for anything better,Just right for an inflatable life jacket.
as advertised, you could find better and you could find worse. the price was reasonable and it's easy to use. Delivered in a timely manner, no complaints.
