I tried mo's a few years ago. Got ripped off with them not sending what I paid for. Emailed them and spoke to a lady there. Still nothing off them. Once bitten and all that!! I have heard a few good reports off them but I won't use them again. This of course, could just be a one off occurrence but because it happened to me direct, it has stopped me using them. They do seem to get a lot of recommendations so they can't be that bad all the time.
The amount I use though, I am just as happy buying the odd bits from my local tackle shop.
