When it comes to price it cannot be beat. But lets give it praise and knock it for what it deserves.
Pros
Great Feel: I think the cause of this is that the gauges aren't labeled consistently compared to other strings. 17 gauge is really 17l, so everything is a little smaller than it should be.
Very Cheap: ehh, no need to discuss this.
Pocketing: Ever punched an old mattress? Kinda like that, it doesn't hurt. In fact you're more worried about the mattress than anything else. Good Pocketing. This is almost a con.
Cons(Oh Boy)
Tension maintenance: 2 Hours, if the strings don't break first.
Spin: Surely you jest, this is a simple bare bones poly. Friction and notching eat this stuff up.
Stringing: I imagine this is what stringing a spaghetti noodle feels like. It's tame, and glides nicely as you weave, and then BAM, tensioning the string put a little to much friction on the string and your tugging your mane over lost time.
50/50
Power: It's Poly, low powered like the rest. Nothing to see here.
Control: This string doesn't really lend itself to control. More than a synthetic gut, for a little longer sure, but then again you can put spin on synthetic gut and it's a more worthwhile experience than this is.
So in conclusion, make sure you have your own stringer before you buy this stuff. You're more than likely gonna have to string after every 1-2 hittiing sessions. If you're not hitting topspin this might last the normal life of your typical string.
