Cheap but useful gadgets - Travel Scales

These are essential when packing your suitcase when going away on holiday. I prefer analogue over digital as they are usually much easier to calibrate and I just trust them more. These are available for less than £5 on eBay or £7.50 on Amazon.

I also stick them in my hand luggage for the return flight. They are probably more useful for the return actually with all the gifts and other things you return from your holidays with. The last thing you want is excessive extra luggage charges or even worse, the embarrassment of having to empty things in the airport and bin them.

A few tips are just to buy cheap towels, toiletries, flip flops etc that you can leave in the hotel to save weight.
