This gives very good speed, good at most of times.I am quite satisfied and recommend this product.it is much better than others, I m using since few months.its. it works on low voltage also, say in trains at 110volts.my experience is no doubt quite good and worthwhile. now the cons.they revised tariffs all of sudden.offer 5 GB instead of 20 GB as per original offer.This will have disasterous consequences for the company, besides legal.i am sure uses have and will protest.Now I for one will NEVER recommend it to ANYONE.
Reviewed/Edit on 30 nov 2017.As I predicted, company have closed down.They were giving legal notices to users for their own problems.eg revised tariff, unilateral.This happens in corporate world.
