Hi munchito.......

I haven't done this myself and i'm not sure about Spain and the islands but, i wondered how much so i had a look at Parcelforce and the cheapest rough estimate for sending a Hinari WM005 is coming in @ £43.65 although there wasn't a send link on this estimate (you have to take the parcel to a depot "international standard for non account holders" no collection available for economy service)

£60.05 was the next price with a send link

I added 10cm to the advertised dimmensions and 2kg to the weight for packing although amazon advised the boxed weight as being 10kg so you wouldnt really need to add this extra 2kg.

Hi,
You could try Federal Express. They are listed in yellow pages or their website is http://www.fedex.com I have previously used them to bring a computer from UK to Spain mainland. They were very reasonably priced and very prompt. They usually provide a "crate" for packing and a door to door service. It cost £58 inc. VAT and that was an Xmas collection in UK for New Year delivery in Spain a couple of years ago. The islands can be more expensive as surcharges are added for import/export.
Failing that would it be possible for you to buy the appliance in Tenerife? You wouldn't have to worry about changing plugs, etc.
