- Shape (elongated tube) and light weight are convenient, it can fit easily in a pocket or small bag;
- Taking with 4 adapters that accompanies (unfortunately a bit shaky) has the advantage of being in one piece (reversible), avoiding to lose a part or not having the right under hand when needed;
- Its sober style makes an elegant object, which does not looks good next to the hight-tech equipment reloaded.
As for small defects, we regret the operating instructions written only in English and battery life that does not reach the peaks. "Smart Zone 3000" is certainly a very good product offering universal accounting and very good value for money.
