Yes they stick on really well. Not meant to take on or off like the Barnett but I tried it on three different guitars over a week period and when you take them off they do not seem to scratch or mar the french polish at all. Taking the support itself off of the guitar or separating from the velcro strips is not easy at first as it is really meant to stay attached and folds to fit in the case(depending on how tight the fit is). It does not come off as easy as the Barnett support but it does go onto the velcro strings easily and you do not have 2 heavy magnets inside the guitar. it does not harm the finish like suction cups do and it holds the guitar in place very securely. SoloDuo does 60 concerts a year and said they have never had an issue at all.
