I wasn't sure whether this was a 160W bamix (since it was £20 cheaper than the Gordon Ramsay titan bamix), but having received it, it was indeed a Gordon Ramsay branded bamix at 180W with the 10 year guaranteed. Unfortunately, the DVD and recipe book were missing, so Amazon had to send me another one. This was quite troublesome for me, as I then had to return a parcel back.
Overall though, this works really well, and I enjoy using it (for smoothies, chopping veggies etc.). I wouldn't recommend using for large vegetables (you'd need to dice it beforehand). Generally it's a very handy tool, and should last the 10 years, as long as it is maintained and looked after. Bamix provide maintenance advice, e.g. to oil it occasionally (but with a special oil possibly 3-in-one), and to use pinchers to tighten fittings if it loosens over time.
I would recommend always to remove the attachments before washing under the tap, to ensure all the blended food is washed off.
Hopefully it will last for many years to come - I'm impressed that some people on the internet had said they'd had theirs for over 30 years - hopefully they were true comments.
