Compact and useful tool

I bought this to carry with me when I am out and about on my cycles. It is small yet has several useful tools to use in the event of a breakdown of some kind which I will be able to deal with at the road side. Haven't used it yet but it is reassuring to know that I have it with me just in case. It appears well made and up to the job for which it is intended. I would recommend this tool.

Lacks in the important parts

The tool is compact and made of a high quality, I thought it was the perfect tool. My view on this tool was then changed on a hot summers day, after a long ride I intended to participate in drinking a chilled beverage only to realise that the bottle opener was totally useless. The 10mm spanner was actually better for opening bottles.

Appears good

I have not used the product yet
