"Saved me from at least 12 tickets now!!!"

OK, the compass does not work well at all. I am over that because the the performance from this unit has been great. I am a traveling sales engineer and I put on 2,000 mile per month. I bought Cobra from some kid off Craigslist for $80.00. By far the best $80.00 I have ever spent. Sure the cobra will go off when you pass a Wallgreens or other building with automatic doors, but around the city and highway, as long as you know what band your county cops or state police us, this cobra is AWESOME! This cobra has got me out of at least 12 tickets already. I speed all the time, I have a Bonneville SSEI with some bolt on mods done, so you know I love to cruise at 90++. Can't tell you how many times I have traveled down 80/90 or 94 coming out of Chicago and running back to MI and this cobra goes off only when it is supposed to. Yes sometimes you get cross dectection from another road next to highway or whatever, but that meas you just slow down for a bit and then speed right back up.
I would recommend this unit to anyone. In fact I just bought a second one for my girlfriend who has an even heavier foot then I do. LOL Great product for the price!
"Consider a later model"

Cobra 9940 seems to work well for the bands it covers (at least I get lots of false alarms, probably due to cell towers and similar things), but I've been by at least 2 speed traps in NH where the gun has been up and on me without a response, so I suspect they are using newer technologies. If I had known, I would have shelled out more $ for a later model.

Ok for the price. Alerts when the situation is so close. Need to alert littler farther distance. Intelimute is good.

For starters it does pick up radars at a good distance the problem is it picks up everything else to. luckily its not an annoying sound when it goes off if you turn off the voice alert. I think for the price its a good product.
"Very Nice Detector"

This is the second detector I have owned, my old one stolen from my truck when it was at the tire dealer overnight (They don't know how to lock the truck or set the alarm apparently). I am far happier with this detector than my old one. It is more stylish, the speaker is clearer, the screen is sharper and it functions well too.
I received this detector as an exchange for an earlier Cobra I sent in for service. Honestly, among diehard radar detector enthusiasts (yes, there are such folks) Cobra detectors don't have a great reputation. Cobra attracts a lot of first-time detector buyers with loudly-advertised "features" on their units. Truly, many of these don't have a real useful purpose.
Honestly, Cobra has made strides toward a better detector in this and the last generation of it's pricier units. Detection range is on par with other units you might find in this price range (or even a bit higher) with the exception of one of the widely used Ka frequencies. Several folks who've tested recent Cobras have reported a glaring lack of sensitivity to the 35.5 Ka frequency. This COULD be bad news for many folks out there as this is one of the more widely used of the Ka frequencies. However, if this is not in use on your commute, the Cobra 9940 is an acceptable unit for the daily commute. It's range is adequate although not on par with the the Bel Vector series which is priced in the mid to high $100 range. Whistler also makes a trio of detectors in this price range (XTR-690, XTR-695, and Pro 78) which tie the Cobra on detection of some frequencies and surpass it on others. Certainly, Whistler's units appear to excel at all Ka frequencies. If you can make due without the flashiness of the Cobra units, the Whistlers are certainly worth a look.
In short, this is an adequate detector for many drivers who don't surpass the speed limit by more than 8-10 mph. However, don't count on it for much more than that. But then again, a radar detector is just one tool to use in conjuction with one's own judgement when electing to surpass the speed limit.
