I use the ocaz for about 6 months, I have yet to benefit from his cot portable and there is much interesting for trs!
The biggest dificult LIEA PXR4 use is in viewing the pieces, but at the same time it would take a computer to have it all under the eyes, so it's not so much as a dfau a!
I bought it for 160 euros ocaz since I bought a smart media card, I do not feel at all for having wasted my money and I do it again this much choice!
