Workswell wcb-m-145 / wcb-m-299

[NB87]

Does anyone have experience with the Workswell bikes in general and more specifically with the wcb-m-145 or 299?

I like the frame but since I can't find any real opinions/experiences about these frames I'm not sure if I can trust them.
I also would like to know if anyone have experience with Workswell's aftersale service.. is their warranty any good or do they leave you in the dark after buying?

I do not have experience with the wcb-m-145 or 299 but i have owned the wcb-m-062. I raced the Frame for 3 Years before the right Chainstay snapped.
Both Frames are sold by 2 german Brands: RaceXtract and BQ-Cycles. I Know a few guys which ride the Frames of those Brands without any issues.
