Rating: - Doesn't work well..
I used to have a Motorola RAZR, and that phone was crap--poor reception and slow response to keypresses. While waiting for the 1st gen iPhone to come out, I bought myself a cheap Nokia to hold me over. I was amazed at how well that Nokia worked, and that sold me on the brand.
I got this Nokia HF33W for my wife's Highlander. It's convenient because Toyotas shut down power to the lighter when they're off, so the bluetooth kit is on only when the car is on. Unfortunately, there just aren't many bluetooth kits designed to plug into the cigarette lighter--at least not from a reputable brand.
After many months of experience, I'm very disappointed with this device. First of all, you pretty much have to use the loudest speaker volume setting to hear people at a comfortable level while on the road. But that's the least of its problems. The bluetooth connection does constantly drop. This happened with both my wife's old Blackberry and her new iPhone 3G. Most of the times I call her, the calls would get dropped within a few secs of answering. She'd call me back with the handset, and there'd be no problems with that, so it's not a reception problem. The mic sensitivity is far too weak as well. On the rare occassion that I'm actually able to have a conversation through this device, her voice comes through as being very faint and distant.
Like a previous reviewer, we're going to replace this with a BlueAnt. It's too bad they don't have a model that plugs directly into the cigarette lighter.
Rating: - Convenient but not perfect
This speakerphone is very easy to set up and convenient to use. Because it is just plugged into the cigarette lighter it is on whenever the ignition is on and you never have to worry about charging it. It does have to be located wherever your lighter socket is, so it wouldn't work on some cars, but works fine on both cars I tried it on. It is easy to hear, but the microphone is a little weak, and of course your voice fades if you look to the left while talking.

Easy to install and it works well enough. Speaker sound quality is not great, but it is loud and understandable. Mike pickup seems to be better than my more expensive EGO Cup (also a 12 volt system). Like my other 12 volt system, how loud one must talk depends on the amount of noise in the car. Normal voice level when car is at traffic light and low speeds, and have to talk loud when on freeway, even with windows closed. However, people on receiving end say what they hear is easy to understand.
Agree with others that the unit does not feel substantial. In addition, on my car, the fit into the socket is not snug.
Rating: - Speaker power too low
This works very well with my Nokia N75 but the speaker power is too weak when I'm driving my noisy Mustang GT. It's little bit strange because from 12V battery you should able to get 3-4W to 8 Ohm speaker. I'm going to open the case and change speaker driver if possible.
I think that this is not Nokia design because usually they do not design or manufacture any accessories. Usually Nokia specifies everything very carefully to OEM manufacturers so I'm surprised to see that output power of speaker is too low for real application.
