[EX Q]: This is an excellent product. Much better than the hard plastic ones found at most stores. I am very happy with it and highly recommend it.
[EX A]: Good Review

[EX Q]: When i plugged in on first time, sparks appeared from it, as soon after connecting, some electric shocks came out. The charger seems ok but obviously this is not designed for Lenovo Vostro 1520.
[EX A]: Bad review

[EX Q]: I was excited to get an mp3 player like my friends have... but mine started having problems within a couple of weeks so i returned it and got a refund. You can buy these in stores which i did when it stopped working. the only reason you would want this is for people who are on their phone all day then have access to internet or music at work. Otherwise it's not worth spending money on. :(
[EX A]:
Bad review
