"The tacky but thin topsheet on Nitrx 4z gives you the
advantage of heavy spin on serves, while being more forgiving when
receiving spinny shots. High control is offered for blocks and counters.
Nitrx 4z is suited for a power driving offense, and works well in a
third-ball attack game. Made in China. ITTF approved.

Killerspin Nitrx 4Z Review:
Review: Nitrx 4Z (43deg 2.1mm
black) on a TSP Balsaplus 4.5 blade
1. The reviewer:
Intermediate to high level club level player, modern defender (Chinese
style looper on FH). Blade TSP Balsaplus 4.5.
2. Physical Properties:
Simple but nice and neat packaging. Sheet looks of very good
quality, very neatly cut around the edges. Has a thin plastic protection
sheet which reveals a soft and virtually non-tacky and very smooth
topsheet. Measured hardness is 41deg (with respect to other rubbers in
the Sponge Hardness Table).
Speed of the rubber is pretty decent, and feels quite linear like most
Chinese rubbers. It does not quite have the speed of Outlaw, but
probably only about 10% less. Since the topsheet feels non-tacky almost
immediately after the plastic is removed, it does not have the dead feel
that most tacky rubbers have on low impact.
It comes off quite fast on fast loops & smashes.
Spin on serves and chops is very good, typical of Chinese tacky rubbers.
On loops the spin was above average, but not high. The makes it more
suitable for a loop/drive style game than a pure loopers style.
Control on this rubber is excellent. It feels relatively insensitive to
spin, similar to euro style rubbers with grippy topsheets. The soft
topsheet gives you a bit more dwell time, which gives you that extra
control when directing your loops.
6. Other Playing properties:
Throw of the rubber is medium+. It does not have any glue feel or sound
like a glued rubber. the sponge is firm enough to not bottom out on even
the hardest hits. It does not feel like a Chinese rubber, it has a euro
feel about it.
I'd compare the rubber to a cross between the Torrent and the Outlaw.
It's both faster and spinnier than the torrent, but the feel and control
is similar. it's almost got the speed of the outlaw, which is quite fast
for a Chinese made rubber, but not quite the spin and lower throw.
8. Other comments Other unique properties...
This rubber is Chinese made, but the quality is among the best Chinese
rubbers I've seen. I've only seen 2 sheets of this rubber, and sponge
hardness was virtually identical from which I conclude that the quality
control is likely to be quite good.
Although it's a little more expensive than most Chinese made rubbers, if
the properties above suit you, and you're after more consistancy for your
rubbers, these are worth considering...
