This looked to be a good idea from the pictures on-line, so I thought I would give it a go. Well once I got the hang of holding the device, rotating the wheel and pushing the aerosol can at the same time it was great. No mess or overspray on the wheel or tyre. It will save time in cleaning up tyres etc. A great idea that works. Cleaning and lubing the chain is no longer a job to put off.
