I use this in the shop for bleeding hydraulic brake systems on bikes. I used to just use a simple spanner and it would intermittently fall down (and sometimes take the hose off...big mess). Even if the spanner worked, it would not easily enable proper torque setting on the (somewhat fragile) nipple connector.
The MWF-3 has both 7mm and 8mm wrenches and both are equipped with a 3/8" socket that you can plug a mini torque wrench into for sealing up worry-free!
I needed to R&R the rear brake caliper, and therefore had to get the right tools. This wrench has the sizes I needed, and is overall a quality tool. I did have to file down the outside of the 7mm side because it was a little too fat to fit between the bleed screw and the body of the caliper. Once that was done it did the job well.
