I recently bought a second one of these, because I lost the cap for it :( but it's worked great for me so far, it's just enough to open up boxes and cut tape and plastic, without being too sharp and dangerous. I haven't used the pen much but I did test it and it works fine. I think having this on every keychain is a good idea
Can be used on camping, to work and have a clear light everywhere. Nice battery as well
It's really bright . Good product for the price
Chauffe un peu mais fait le job
Haven't had it long but not disappointed works very good!
top light, very small and very powerful
