The only comment I have is that when I need to extend the spool, the glue is too tight and will not allow the string to come out, so I have to stop and remove the cap and undo the stuck spool string to get going again.
We go through another of spools and this is a great program. Only problem is to not order during a hot summer. The line is plastic and if it's too hot in transit, the line sticks together and makes it very difficult to use. Better to buy the spools in the cooler months.
