I have two of these (one in the S8 and one in the missus XC90 V8).
They are nothing short of brilliant.
I've jumped the S8 several times, jumped FIL's 4.5L Patrol, jumped two different 4.0L Falcon's with
dead batteries...
I bought my sister one after a battery mishap, and I've sold several others on the concept after demonstrations.
On top of that, they were also used extensively over a 3-4 day period when we had power lines down after a severe wind storm - each one was good for a day simultaneously charging a phone and a tablet to keep the little daughter happy watching teletubbies! I simply alternated charging them at work!
Their CCA capacity is a little overstated. The cables are only 5mm, so can handle about 200-300A max. So claims of 800CCAs is a nonsense. They are still powerful enough for V8's (and clearly V10's) though!

The Kincrome one seems to last a little longer (maybe), so the Saoko one off eBay may exaggerate it's capacity slightly - it's still an excellent device!
