Does what it's supposed to do

We bought this strimmer after our old 1 broke. It comes with a blade on the strimmer & 4 in the handle. On 1st use 2 snapped so we thought it best to order more. This was not easy but we eventually found a stockist. I think the covid situation has affected stocks as the parts come from Germany. As things get back to normal it should be easier to get them.
