Bought a nova trimmer a few months ago, it worked well as advertised, the battery was good too, and was a good deal for the price. You could always find nova trimmers and personal care products for less than 50% off, I highly doubt it.
But after normal usage, I happened to slip it once and then it stopped working.
The blades seem to gather hairs and require cleaning now and then.
It does work well, but being a china product it isn’t reliable or such.
