BoldonLad. I have also purchased one from Amazon, tried it on my mountain bike tyres yesterday seems pretty good, will see how it lasts
I bought
this one off
Ebay. £28.91.
It arrived today, Thursday, 15th October.
First impressions are favourable, ie it appears to be well made. Not too heavy, and, not too bulky, it will go in my backpack no problem. It comes with adaptors for Presta and Schraeder valves, plus another couple. It has a built-in torch. There is a neat little bag/pouch to carry it all in.
So far, my one complaint is, the size of the display, my 73 year old eyes can read the numbers OK, but, reading the units (psi, bar, etc) is a struggle!
The instructions. are, as with many Chinese products, in need of translation to true English, but, operation is simple enough, so, instructions not really needed.
It is currently charging (4 hours before first use, thereafter 2 hours, according to instructions).
We have a mixture of bicycles, ie 2 x hybrids with 700c 35 tyres, 2 x folders with 20" tyres and an Ecosmo tandem with 20" tyres.
I will report back when I have actually used it to inflate a tyre!
