Multifunctional Sink Wrench , Alloy Steel Faucet Installation Tool with Head for Kitchen Bathroom Plumbing, Pipe Fitting Tightener and Remover, Basin Wrench for Home Maintenance Repair(1 pc)

I have seen various ads for these and when I searched, this inexpensive one came up on Walmart site so I thought I would give it a try. It did not work to tighten my new R.O. faucet nut as it was too small. I guess I should have double checked the "wrench" sizes. I will say though, that despite it not working for my needs, these are cheap plastic. I bought a durable basin wrench (which is adjustable) for a couple of dollars more. Would not recommend this tool and would consider it a gimmick.

The title of says alloy steel. My multi functional sink wrenches that arrived were made of plastic. Maybe a glass fill nylon, but not steel. This tool set may work in new builds where nothing is frozen on. But on older house plumbing, they will not handle the torque required to break loose a frozen faucet nut.
