Switch is soft but can be stiffened
I was looking for a sturdy light, with replaceable batteries, for my keychain. I was disappointed that the switch on this flashlight was too soft. I wondered if my experience was common, so I searched the internet and REI, and found these reviews mentioning the soft switch.
I decided to look at the inside of the flashlight, to see if I could stiffen the switch. The battery replacement instructions on the package gave me courage. Opening the case is not too easy because it is strong and tight. It requires prying all around with a small screwdriver. I carefully lifted off the top half. It seems like the LED is secured somehow, which is good, so it doesn't fall out. But you still need to be careful not to let the batteries fall out after you remove the cover.
Here is what I did to stiffen the switch:
After removing the cover, gently lift the thick wire (LED terminal) and bend it straight upward a slight amount, so when you let go it points up at a 10 or 20 degree angle (instead of lying nearly flat on the surface of the battery.)
Then carefully put the top half of the case back in place, lining up the little pins that need to fit into their matching holes, and squeeze it together. The case is made of amazing indestructible plastic, which is good, because it requires a lot of pressure to close it again. You have to pinch it from all sides to get it closed all the way.
I haven't had the light long enough to rate the durability or long battery life, but I am expecting they will be good.
Without a light...
I went rock climbing to Yosemite last Labor day and got stuck on the rock a little longer then me and my cousin anticipated. By the time we got to the top the sun had set and all we had was this light. It lit up the path just fine we used it for almost three hours strait.I still haven't changed the battery which is wonderful!!!
I have one on my key chain now to as well as an extra one on my harness...
I think everyone should have one.
The light beem is very bright and is easy to turn on and off. I have not had problems with the switch...I've had it for two years now...
I have a few of these - one on each pack and a couple clipped to my tents. They're small enough to almost use like zipper pulls, which means it's easy to have them around all the time. Bright enough for tent lights or to find your way around a campsite. The "II" version has a switch that allows it to stay on without having to keep thumb pressure and makes it useful as a tent light.
Looks Delicate But Performs
Just bought a few more of these for my wife's girlfriends. I first hesitated buying because the LED lamp seems so exposed and delicate. Previous recipients have successfully used these for two years on key chains and we all know how much of a test that can be. Immediate, intuitive operation is a must in this category. All our friends are grateful.
Great tiny light
I have been using these small clear bright lights on my key ring, clothing and bag zippers for years. I also have several to keep with personal items for travel. I always buy the model with the on-off switch. They last a long time. The batteries are difficult to change, so I usually just buy a new Pulsar II.
I carry this all the time
I carry this with me on a key ring, in my purse - all the time. When I need a quick light unexpectedly, it always performs. It bounces around and is scruffed against other things and has never turned unintentionally been turned on. Very convenient and reliable. I have given several as surprise gifts.
My Brightest Keychain Light
I'm a bit of a flashlight enthusiast, so I have a lot of similar items. This one is my favorite, and lives on my keychain for everyday use. Get the high visibility bright yellow version if you keep it in a dark purse or pack.
Princeton Tec Pulsar 2
I carry one on my EDC,its bright and the stay on option is a bonus. I can just turn it on and do whatever it is I need to do without having to hold on to it.
Good emergency light
I much prefer this version of the pulsar because of it's on/off switch. It sure beats squeezing if you have to keep the light on for more than a couple seconds.
great little light -- so light you can forget you have it, but good for myriad applications in most conditions. I've bought so many I should get a bulk discount.
