I am an apprentice automotive engineer / mechanic with a large automotive company and, although the quality of the tools is not as good as I am used to, this is genuinely a must have for any motorist.
The tool bag is very innovative as it has Velcro strips around it which secures the bag firmly to the floor of the boot to stop it from flying around.
The jump leads are nice and thick with big sturdy clips and the screwdrivers, wheel wrench, warning triangle and tow rope all seem to be sturdy.
The air compressor is surprisingly good, I tested it as I have had bad experiences with cheap tyre pumpers, however this didn't blow any fuses and provided an ample pressure, however whether it would reach 300PSI like it says is another question.
The biggest let down was the adjustable spanner which had lots of play and felt tacky and likely to break if you try to undo a stubborn nut, plus the gloves look slightly anorexic.
Overall I would certainly recommendatory this product, it could spend tens of thousands of miles in your boot unused but one day it could save the day.
