I just bought an Avenger M1 from Robin (emale) and he has been a great guy to deal with.
Firstly he was willing to sell to me in the UK (he's in the US), which was very nice.
He then packaged the watch very well so it would meet the Parcel Pro insurance standards.
He communicated with me regularly through email and was a gentleman throughout.
To top it all off, he even set the watch to UK time so that it was showing the right time when I got it out of the box - nice touch
I would happily deal with again.
