Ordered this light in January 2015. First impressions were awesome. Super bright for its size, weighs next to nothing, so it was a breeze to hang on the lanyard I wear at work. I walk into a lot of dark buildings for my job, and this light has saved me from groping around for light switches countless times.About a year in, the strobe feature just flat stopped working. Not that I used it much, but nevertheless, that's a feature that just disappeared. I also noticed that the outer coating on the rubber bits (button, USB dust cover, keyring tab) seemed to be peeling away.18 months in, and the rubberized piece that holds the keychain to the unit just fell apart. No stress, no trauma. Just fell apart when I picked up my lanyard from the seat of the car. The rubber tab it connects to was glued to the shell of the unit, and the hollow piece on the end just crumbled away.The unit still works great as a super-portable emergency flashlight, but without the keyring connected, it's somewhat less useful. And it looks like there isn't much room inside the case for me to attempt to drill a hole & secure a keyring some other way, so I'm not left shopping for a new mini light.If this unit had a more secure/durable keyring, it would be 4 stars. The strobe going AWOL took another star for me.Very nice little light, surprisingly bright and lasts a long time on a charge.If they could change two things this would go from a nice little light to an awesome little light:1. The brightness order. Powers on in high, then you hit the button again and it goes to low, hit the button again and it turns off. I think it would be much better to come on in low, then high. Very often I will hit the button thinking I have turned the light off only to find it has been in my pocket running on low for hours.2. The low needs to be lower. I would say it is more like the light has medium and high settings rather than a low and high.I had one of these given to me as a gift a couple of years ago and I lost it. I love the fact that it's rechargeable and that I don't have to keep holding the button, like some models require. This is a good light for your key chain.GOOD PRODUCT, BUT BUTTON SOMETIMES GETS STUCK AND IS REALLY NOT CONVINENT IN THE DARKAfter 2 months of intermittent usage, recharged twice. After second charge, light would not turn on. Tried charging again. Light flashes at 10hz (very fast) . Light does not turn on.man kann nachts damit durch einen dunklen garten gehen - das licht reicht aus um nicht nur den weg ausleuchten, sondern zb auch bäume in einiger entfernung zu sehen (ob es jetzt 10 oder 20 meter sind, keine ahnung). also für so ein kleines ding ausgezeichnet. als radlampe wäre der kegel sicher zu schwach, um den boden zu sehn, aber gesehen wird man damit auf alle fälle. den zweiten modus (high bzw low) hätte man sich sparen können. dünner und kleiner als ein autoschlüssel, stört nicht am schlüsselanhänger.Excelente linterna! es muy pequeña y la puedo llevar siempre en el llavero del coche, para el tamaño que tiene es sorprendente la cantidad de luz que emite y es muy fácil de recargar con un puerto USB del ordenador o un cargador universal. Altamente recomendada.Endlich so ein Format gefunden! Bei mir am Schlüsselbund im täglichen Gebrauch. Sieht gut aus, vernünftig verarbeitet, besteht Speichelproben meines Babys, ist super hell, klasse Auflademöglicheit mit USB- für mich perfekt!Pequeña, ligera, potente y recargable por USB (adiós a las pilas),. Es justo que estaba buscando y cumple bien su función.Ich habe wohl leider eine Montagslampe erwischt. Nach 6 Tagen war sie kaputt!Habe mir sie trotzdem noch mal bestellt... Warte noch darauf und hoffe damit mehr Glück zu haben.
