We have them at work, I think they are pretty much garbage after a few weeks of hard use. I carry my own Pelican BIG ED or a Koehler Responder (which is the best right angle firefighting light I have used). The Survivor rechargable lights are designed to be stored in their chargers, but the batteries gain a unrecoverable memory very very quickly.

If you are looking for a good right angle light, I would look at the Pelican Little Ed Recoil LED Light. The Fire Store is a great vendor also, I do quite a bit of buisness with them both personally and at work.

I just cannot recomend anyone buy a Survivor, Streamlight makes some other very good lights... this just isn't one of them in my experience.
