   Good product so far

Pros: This unit is small and compact it works great in the space where we installed it. It also seems to be fairly rugged. We like the units internal cooling fan, we were affraid we would have to design a cooling system for it. I also believe that the item was shipped the same day as I had ordered it.

Cons: When ordering, I was not asked for a shipping address only billing. It was shipped to our unmanned fire station, the delivery company hung it on the door knob in a plastic bag.

Other Thoughts: We installed this into a surplus military 5 ton truck that we are revamping into an off road firetruck. The trucks electrical system is 24V, we are running the 12V radio and siren with this unit. So far it works great, but we are not done with the restoration of the truck, and have not put it into service as of this review.

   SDC-30 Step Down Converter 24VDC to 12VDC

Pros: good price, small size

Cons: connector tabs are too small to easily accept spade conductors, especially if oversized wire is needed. I'd prefer good screw-down lugs, big enough for 8 gauge wire. Computer-style pancake cooling fans may emit an irritating high frequency sound.

Other Thoughts: I was double charged due to the item being on back order when I purchased it. When it finally shipped, the second charge was put thru. I got i all squared away with one phone call, but BatteryStuff needs to catch these things internally, BEFORE it gets to my credit card!
