Hi i bought a sound driver from Driver Boost for my laptop.I paid 38 euro.It worked for two days and then i had to reload it every time i turned on my laptop.Every time i would email them they would tell me to try this and try that and still it would not work.When i asked for a refund they asked me to the same as before and sill i had no sound on my laptop and i am down 38 euro . and now they ignore my emails.Avoid Driver Boost at all costs.They will take your money pretty quick but want refund it when it dose not work.Learn from my mistake and dont deal with them.
