Received mine yesterday and so far:
I like the ease of programming the scanner being that I had already programmed my 436HP. I just needed to download the new version of the software and then make sure the software was set to the correct model.
The audio and reception is great in my area in Michigan MPSCS on the APCO 25 800MHz digital single site as well as simulcast. I did have one issue at first.The signal strength was full and the stuff I did hear was loud and clear but I the system didn't seem very busy and that's not normal. I started checking the settings on the scanner it's self and I noticed most of the Service types (like EMS-Tac, EMS-Talk, Ham, Law-Tac, EMS-Dispatch) were almost all off under Settings/Select Service Types. I ended up turning them all on and wow the scanner came to life and everything was right with the world! I went back into the software and checked the settings under Edit/Profile/Service Types and sure enough only 4 were checked. It wasn't like that before I updated the software from programming the 436HP so please check that setting on yours. I also need to see if that setting is independent when you change the scanner model back and forth from the 436HP to the SDS100 in Sentinel of if the new version reset them. It seems like I had to turn on the service types when I first got the 436HP too as most of the service types were off.
I do notice the scanner runs very warm when you charge while scanning and when you have it plugged into power even with the charge turned off. I'm looking forwarding to buying a second battery pack and an external charger when they become available.
I'm using mine mostly in the car with an aux cable so I can feed the audio from the headphone jack into my car stereo and it works great. I'm using the supplied power cable plugged into a USB port in my car for power. I found a cute little mobile antenna on ebay that I stuck on the inside of the back window with the supplied double stick tape that I'm trying and on 800MHz. For the price it seems to work great with the SMA to BNC adapter on the scanner. This is the antenna:

I'm not going to talk about the supplied antenna as I never use them. For portable use I used the SMA to BNC adapter with a Radio Shack 800MHz antenna which you can now get from Whistler website if you don't have one.
So far my only dislike is only having one battery. With the 436HP I always had three sets of batteries that I charged in an external charger so I was always ready to go. This will be fixed once Uniden has extra batteries for sale as well as an external charger option.
