    Such a fantastic product! It’s made building my first board very easy and bioboards are really good to deal with answering any questions quickly and the shipping to the uk was super fast, Markus also recommended the haggy pneumatic wheels from another company which I bought and they too are great quality so thanks bioboards (Markus) you’re doing a great job
