I used it for 5 days for my blackberry and htc phones. Worked well but battery went off like 10 pm, so when I went out till late,I had no connection, but overall I had no trouble. Only that it didn't work well for whatsapp call.
My friend who is staying in the house wanted to use it so we gave a try. Actually they serve us with the first deliverly and the good quality wifi! Sometimes the internet was slow, but by this cost it is acceptable.
