Recite the tasbeeh only with right hand or with both the hands, both ways are right. It is mentioned in hadith: count using fingers because they will be questioned on the Day of Judgement what they did and answer will be sought from them and while answering they will bear witness. The same thing is mentioned in the holy Quran in several places that the body, hands and feet of man will be asked what good and bad deeds they performed.
