I have a K3770 running on Mac OS X 10.6.8 I'm renting and also travel locally to work outdoors in South West UK- I did not want the extrta responsibility of putting in a land line and I wanted the flexibility of being able to connect at work as well. Like the other reviewers who rated poorly, although I checked that the product should have good connection in the area that I live in. Although there are very steep hills here and we often have mobile phone connection difficulties in the valleys (especially in the deeper rural areas), phone voice connection specifically where my house is, is excellent. My experience with product: Most pages (even simple looking pages like this site) time-out before they opening. Many pages with server error messages and not opened properly. VIDEOS DOES NOT PLAY AT ALL. The best I can get is opening and sending e-mail. I have tried everything available to me to inprove the connection (moving near different windows, opening windows, re-installing product software on computer, updating all the other software on computer...). After 5 days struggling with it and a lot of time spent, I am sending it back.

I have used my vodafone dongle lite for almost 18 months now on a £15 a month contract, it is excellent! I live in a rural area which most people have difficulty in accessing the internet but I have had no trouble whatsoever. I use the internet every day and for several hours and have never gone over my monthly useage, I don't download movies or music though so if you are thinking of getting one think about this. My daughter has just got the pay monthly version which is exactly the same as mine but without the contract, she just has to top up each month with her £15, she loves it :) The only thing I would like to have known before I purchased the product was how to set the limit as they are set at a very low limit and you get a message saying you have gone over your limits when you haven't, I even went into a vodafone shop to ask but didn't get much help, I eventually discovered how to do it by contacting vodafone online help, it was just a matter of changing the limit on the menu box to 3000 instead of the 50 that is automatically put on there, the same applied to my daughters with the pay as you go version, I don't really understand why vodafone set them at such a low limit why not just set them at the correct limit to start with?? Oh well, can't have it all I suppose!

The set up was very easy and simple it took 5 mins to install and i was surfing on the net. the speed was very good and quick. it doubles up as a 4gb storage unit and u can top up by a voucher of £15 and u just input ur voucher and ur away. the vouchers are long lasting so there is no 30 day limit and the software is easy and simple to use. it's worth buying if you can find one avalible. So if u want one reserve one like i did. I can 100% say go for Vodafone Huawei E156G Dongle if u want a mobile broadband dongle, its fast and realible. it was worth £39 of my money and when i got mine today it was the last on the shelf so it shows they are selling quick.

The signal strength is nearly non-existent the majority of time even in different areas of the country. very rarely would you get a signal that your allowed to use. Sometimes it would switch to the republic of Ireland network and you are unaware of this happening and if you continue to use this obliviously then you can be charged like 40-60 extra each month for barely even using it. This happened to me 3 or 4 times with them.

I feel bad saying this after the reviews that are posted but Vodafone really need to get there act together.
I have just had a dongle lite on a trial for seven days.
I cancelled less than seven hours after getting a very weak connection even though customer service told me the post coded area had very good cover.
The product when opened had obvousily been used before it even had someones Vodafone email address on the disc envelope.
Customer service promised to phone back in the lunch time to help rectify the problems but couldn't be bothered. they even suggested moving me from 3g to 2g a slower connection after me telling them their information was wrong and the area had a poor reception

The Vodafone USB Modem Stick is very simple but effective, just plug in, install the software on the stick and connect, although if you use Vista it will be a little different as you will have to obtain the full software from Vodafone which they do supply free of charge to download. The stick switches between GPRS and 3G whenever it needs to reducing disruption to the user.
