Full user review
"nice and free"
it does help me stay connected.. furthermore, it utilising 2 types of process which is ping and http simulate.. also, it has countdown to the next pinging.. so that we know when it will ping next.. other software, would just sudeenly stop pinging.. and at the end, we lost the connection.. so, this one really work for me..
cannot be stored in tray.. just minimize..
