Adjustable 10-19mm Socket Pro Magical Socket Wrench Mintiml Wrench Replacement Accessories
A part of the review has been auto-translated.
In principle, it can be adjusted between 10-19mm, it was very difficult to narrow it down to 13mm to see if the 10 goes will be found out. But if you set it too big, it'll just fall apart, there's no limiter to keep you from twisting it to disintegration... It's a necessary solution, but don't expect too much from him.
This tool appears to be well made, it would be ideal for home/amateur use. I would not recommend this for a professional mechanic. The item needed lubricant adding before first use. it works fine but does take almost as long to adjust from minimum to maximum as it would to get the correct sized socket from the tool box. if you are short on space eg motorcycle or bicycle then this is an ideal tool which saves carrying multiple sockets. highly recommend for the cost.
