I bought this because it charges through usb. The flashlight worked great for three months and then the switch broke. Now it is useless.

Bought this and it worked great for about 3 months. Then the switch started getting a little flaky where it would work sometimes. Now, 4 months later the switch mostly does not work so I can't get the battery to charge unless. This battery back up is a great idea and helped me a bunch of times as I travel a lot for work. Unfortunately the switch just stinks.
I never dropped the device so I know it's not an issue with abuse.

The flashlight is still working great and it is pretty bright for it's size and price. The rubber strap on the mount broke today. I was just moving the bike and it ripped. I liked it while it worked but, it didn't last very long. It lasted a few months with minimal use. Maybe a couple times a week.

I really liked this flashlight. It is sturdy and bright. I also liked that it plugs in for a recharge. However, it was very expensive and now doesnt work. I had it maybe 5 months and it will no longer shine. It says it is charging but it doesnt turn on anymore. An expensive waste of money.

This light worked for about three months before I noticed the back light went out and the front was starting to dim.

The Flashlight was perfect until it stop working. I received it in on May 30th and in July 19th it stop working. I didn't let it fall or get it wet. I am really disappointed because I really like it and I can't believe that it stop working that fast. I don't my money back, I want  a new P16 NiteCore Flashlight in exchange for the one I have.

Beware of this product. I had this flashlight for about a month before it was dropped once on a concrete sidewalk causing the on/off switch to stop functioning.  The Amazon web page says there is a 12 month warranty, however, when you click on warranty information, is says to contact manufacturer.  It was impossible to locate manufacturer (Ploarnovo) on the internet to inquire about a replacement part. The flashlight worked fine before it was dropped..  So, you may have to consider this a "disposable" flashlight, i.e. after being dropped once, you may have to dispose it and buy a new one.  Rather expensive for a disposable flashlight.

Not a bad light, but the switch began being intermittent.  I traced it to the switch itself and not any contact by taking it apart and measuring the resistance at the switch terminals.  The switch simple does not toggle correctly with each depression  --- when it is on resistance is less than 1 ohm, but it most often it does not successfully switch on and remains at nearly infinite resistance.  I never liked that the switch on this flashlight required so much pressure to depress, either.  The Mag lights have much nicer to operate switches. As the switch is bad, this flashlight will be recycled.

Light works great, but after 3 months and 5 uses, it now won't turn off! Useless to me now. Might consider looking for a new headlamp elsewhere!

great flashlight but after 6 months the battery no longer charges.  I can't tell if it is the battery or the charger that stopped working.  Either way it is now useless

It was great. Stopped working completely after three months.

The flashlight switch keeps breaking loose from the housing and you have to completely dismantle the flashlight to reattach the switch. It works well, but the switch is junk. Be prepared to get the superglue out.

This flashlight works well for what I need. It is very bright. The pivoting head is handy. If you look at plastic flashlights most are way less expensive than this one. The switch is poor quality and only lasts about 10 months of daily use.
