This flash board is hands down the best portable fingerboard I have ever used miles above any other board. Not sure why everyone is slagging it off.
Should have hung onto your mate's one and told him to get another back home.
We have another portable board along side the Mission board that's worth considering...a smaller board.. weight wise it's between 500-600 grams...http://crusherholds.co.uk/portable-fingerboards-hangboards/crusher-send-hangboard
Negatives: quite narrow.
