I know nothing about this gadget except that it was expensive. It has been opened but unused and was a gift. It is not what I expected it to be - I thought it was a normal gadget to ascertain heart rate - not a monitor for a sports person.

So out it goes to a more deserving and energetic person.

I always package securely and only send at buyer's risk. It is up to the buyer to seek compensation should an item get damaged in transit.

I no longer quote postage - I have been stung too many times by unscheduled postage increases.
However I undertake to:

(a) Pack your purchase with care to maximise safety, (b) Endeavour to keep postage costs to a minimum, and (c) Not to charge you more than I am charged.
