After just over a year, this bag pretty much needs replacing.
The stitching has had to be fixed several times, the zips have broken, strap has broken and now the rubber base is falling apart. The reason I got this was the rubber base which I thought would help it last, despite the massive increase in weight this adds. Mine weighs in at 16kg with tools and laptop!
Given how well the blue CK bags lasted, and great experience of their tools, I have to say this is the biggest waste of money anyone can buy. It's not be thrown about, it's not been abused. it simply isnt upto the job.
It's just not designed for field engineers. It's too delicate and simply doesnt last. £50+ isnt an item I'd expect to only last 1 year. I'd expect a £15 bag to last this long. I'm expecting a minimum of 3 years, daily hard use in a mix of field conditions.
DONT BOTHER. AVOID
