I currently hose 100m of Gardiners Thermobore 6mm ID had it since late January of last year and it has been the most durable hose i have used just rotated it 2 weeks ago .
I do run it across some roads but not only one main road in front of traffic lights and have had no issues with this hose at all .
Other hose i have used has sprung leaks and been torn open on roads with cars going over it after about 6 months of usage . Mike
