In my opinion.. the GuangDao is the prime of all VS at the moment.. it has several versions.. the basic n normal unit is already expensive.. dont just think its another non branded products.. but it is the best so far among VS in Malaysia
If You wanna get Pivot.. its a good deal.. For Raizin Blue,but pivot Volt Stabilizer alone wont give much affect.. un less the raizin+ground wire is combo with other pivot product.. But Pivot product really works for me...
if wanna buy.. can try Pivot Raizin, Zaptor,Sard Magic Box... these brands you can get below rm300 with ground wire.. if wanna save you can get ground wire separately.. groundwire got from rm 40-80 for just ground wire 5/7 wire..
