£60 odd for a tap. waste of cash.
That's your opinion and we respect you for that.
For us and several other local windies who all have them, they have definitely saved us money with reduced water useage. Unfortunately, statements like this (reduced water useage) are difficult to quantify as water usage changes with conditions and user mood. Some claim saving of up to 25%, but I think that's way too high.
For me, I hated squeezing the pole hose to stop the water. We used to use on/off taps but they never lasted long. I used to buy 6 taps and fittings at a time which would last the year. That cost the same as an AD.
My main pole has had the Mk2 AD on it since they came out, over 3 years, and I have replaced 3 springs on it at 99p each. So for me, this is a cost saving.
I'm not young anymore and my back hurts when I bend down, getting worse through the day. To keep bending down to retrieve the pole tap on the ground just made matters worse. My right leg is continually numb. I try not to take pain killers, but occassional I'm forced to. So just not having to bend down more than I have to is a big bonus for me and the main reason for buying ADs. For me its the best accessory invention in the world of WFP. For others, it isn't.
Just for the record, I tried to strap the tap to my belt - didn't work and ended up with a wet leg. I also tried to put the tap over my shoulder and rest the tap on my chest and even wrapped it round my neck for a bit. I tried to hold the tap in my hand as per Alex Gardiner's how to video, but wasn't comfortable doing this.
So I will continue to recommend buying one, but it will always be because of my experience which will be different to yours.
