Review on Efficient Clearing with General Pipe Cleaners 1-1/2CG ClogChopper - 1-1/2 Inch Part Number by Non Martin

This is an unspecified 1 1/2" diameter; rather it's closer to a 1 1/4" diameter. I suspect it's smaller for getting around corners etc. I needed something exactly 1 1/2" diameter to clean the drain pipe, so could this thing didn't do the job I bought it for; and was therefore a waste of money. In the end, believe it or not, I used a 1 1/2" hole saw on an extension to clean out the pipe and it worked pretty well. To me, this shop was a waste of money. However, I have it still keeping it because i have it now and i might need it one day for my drain snake to loosen the drain retainer.. i have concerns about the tongue seam; i hope the weld doesn't break and the ball doesn't fall down the drain pipe because that would be terrible of course.While it's a waste of money at the moment I'm giving it 3 stars because it might be useful in the future to solve a backup problem.
