Great for using under small basins as the head and arm that grips the nut is much smaller than other tap spanners.

This tool can loosen different size fittings and if you pop the end off and reverse the jaw you can tighten the new one too.

Great tool

Great tool. The teeth grip very well and its slim enough to fit under most sinks

Exspensive, difficult to use.

I purchased this to remove a difficult to get at bath tap. Because this hasn't a sprung loaded jaw, it was almost impossible to get it to grip the bath tap nut, especially being upside down, one handed between a bath and a loo. It didn't work for me.

Valuable tool

Wrench works once I worked out how to actually use it! So more of an issue with the user rather than the wrench. Seems well made and will be very useful when it comes to refurb kitchen and bathroom.

Handy to have.

Excellent Quality Product, however i couldn't fix the tired old boiler with it, but then thats my fault for marry her.

Great tool for fitting basin taps etc, gets in all those hard to reach places. I had a cheaper version of this type that was useless.

Our toilet cistern was leaking from the bottom and there was almost no space to work in.

This tool makes the job possible. It's well made and built to last

For those hard to reach spots!

Brilliant for those hard to reach, in tiny spaces nuts that need undoing behind basin and under sinks. Easy to adjust to the way you need them to turn and easy to change the size grip needed.

I have been struggling for decades without one of these!
For hard to get to gland nuts under basins, baths, cisterns - you need an adjustable wrench.
This one is high quality (reflected in the price) with nice extra features: 2nd jaw held neatly on bar end, bar end has 1/2 inch A/F hex head to use 1/2 inch socket wrench for extra torque, Tommy bar removable if necessary. Would recommend as an essential addition to your plumbing tool kit.

Excellent

Good but could be better.

I bought this as the jaws were slightly slimmer than my old wrench and therefore easier to use in the confined area around bath taps. Whilst it fits better in the limited space, the fact that the jaws are not spring loaded means you need to get hold of the jaws to latch them onto the nut. It is an improvement over the old, thicker wrench but could be better if it only had a spring.

One and only

I've always wanted one of these, I was plumbing 50 years ago, never had one till now. Got a job I couldn't have done without this tool. Need I say more, saved my bacon.

Every toolbox should have one.
