Been using one for the last two months now
Only use it when doing alot of pole work usally above 18 feet
Look a prat with it on but i have noticed less pain in the neck area
If you are doing alot of pole work it is good to wear one but you will not wear it because you cannot be bothered or you look a prat
We do not know the long term problems you are going to get with WFP,but neck pain is going to be high on the list
Alot of the bigger companies have allready put in place the use of this product by its emplees,part of the risk assesment
