Used but I've never fallen on it, just did some test falls wich were about fall factor 0,1 to 0,2 to be sure it did its thing.

The device performs perfectly as the first day, I could send a video showing how it slips on the rope and how it locks when I yank on it.

It's got some scratches but it it's just a little aestethical issue, there are no razor edges nor anything wich could suppose a danger to the user.

Be aware that over the price there will be a charge involving shipping costs, insurance and customs, those will all be assumed by the buyer and we will negotiate to get the cheapest possible shipment having consideration of the safety 

Those costs will be(*approximately):

50-500€ / 55-540$ for the shipping (most probably 90-115€ / 100 - 125$)

*I'll be placing the biggest price wich will be discounted from the real price as soon as I know the destination

55€ / 60$ for the insurance (in case the customer wants it) plus whatever the customs tariff from your country involves
