It's worked twice now for two completely different products, one was a Traffic Exchange and the other was a personal development product.
I haven't got any testimonials yet because I haven't asked for them but I will do in future, thanks for the advice on that by the way .

My Guarantee is pretty much if I don't produce the results then I don't take commission.

Well I use a system to promote there products by giving extra value, I write the email campaigns and get everything in line for the person and then watch it all work out.

Best,

Adil.
