Very happy with mine!!

First impression right out of the box: wow-this thing is heavy! Of course weight doesn't mean quality, but the external build quality and weight of the 940 makes my two Cobra detectors seem like toys.
Since I've had this detector, my impression is that I am detecting Ka at noticeably greater ranges as compared to the Cobras. Also, it only took a few days of use to notice that the 940 falses a lot less too. Overall, the 940 is a much better detector than the Cobra 1010, itself a detector that has a similar list price.
I like the ease of use of the 940, but one thing I don't like is that the voice warning for the band being detected is at a constant volume, which is somewhat low. I think the voice warning sound level should be able to be adjusted up and down in keeping with the sound level of the beeping. At least the sound level of the beeping has great adjustment. One thing that I found interesting is that you can mount the 940 upside-down, and than adjust the display to also read upside-down.

I strongly recommend that anyone who wants to purchase a detector in the sub-$200 range consider Bel first, and to stay away from Cobras of any price. In the sub-$100 area, look at the Bel 910. In the low-$100's, look at the Bel 930. If you can afford more than $200, then you also have the Escort models to choose from, which have always had great test results. In fact, if you don't want to spend the $300 it takes to buy an Escort Passport 8500, then just stick with Bel....
