Silverline, I thought was a quality brand, the chain link on the stop key were nearly cut though on several links ( I bought 3 of these), also two of the the cramps winders are off skew, they tighten up alright but they're like cheap seconds, saying that I have used them and they did the job.
Thread so bad, had to put in vice to turn to try and loosen it. Then end securing part of head broke, all before used.
Had to spend an hour messing around with it to get it useable.
Was cheap, so get what you pay for.
