It’s one of those items that you hope you never have to use, but you want to have confidence that it work and this fits the bill

This strobe is used as an emergency signal tool when out hill walking and is also perfect to keep in the car in case of accidents.

ACR makes lots of these safety devices in different configurations so they are not new to this business. It works perfectly no problem. It suggests a little silicone around the battery seal as it comes dry.I saw a negative comment about water getting in and perhaps this step was not followed. By some real stroke of luck my Sterns SAR PFD has a pocket on the shoulder strap that this fits in like it was made just for this unit.It's approved by Canadian standards. It works well and is quite bright. I will buy the auto version in the future, good to have two. There is another brand made by a company that makes survival stuff but when your lifedepends on a piece of emergency equipment I prefer to buy from a specialist.

Needed a replacement for my firefly from like 15 years ago and its the perfect size and super easy to set up .... I live in a hurricane battered part of the world and this is a critical part of my EDC and Go-Bag!

Order 2 units. One was loose in bubble wrap but "seem" new. The other one in original box. Time will tell if it was a good move to order online.
