"They do the job. I don’t think the biscuit itself could be bettered. They are nicely abraded and have a consistent feel and thickness thereby making repetitive work such as adhesive application and insertion easy to carry out. If I had a criticism it would be that I would prefer a larger range of pack size; 100 biscuits are far too few for most jobs. I would also prefer the biscuitsto come in a sealed container as ‘they go off’ in damp weather (expand). They are very tough; I have not known one to fail as yet. They don’t splinter/ disintegrate even when drilled through."
