I bought nova nht 1055 model 5 months ago but after using only one month it is fully damage. It gave me one year warranty service but I do not find any service centre in my local area. Whole company is cheater. Its most bad service is battery. Its battery takes full charge 7-8 hours but the machine is running only 20 minutes. Its blade not giving smooth trimm. It is not a effective product. It also not a user friendly. Its price was 450 rupees which is waste of money to me. This product is totally crap. So I do not buy novas trimmer in my life. It is very worst.
