Pros
  • modded wheels allow for maintenance-free operation, without performance degradation
  • tbh works flawlessly, also with the pocketable 24V-powerbank
Cons
  • impossible to produce short or slow balls with high spin rate
  • questionable longevity/durability (not a factual con yet!)
  • cannot be repaired; the engineers didn't have "let's build and design to last" in mind
  • requires working WiFi or mobile internet connection
  • overpriced (you pay for functional benefit not the massproduced value/quality)
The extremely filigree detailistic internal plasticky CAD construction💅 doesn't make the Nova suitable for club use or professional use imho; the engineers didn't have "let's build and design to last" in mind rather than "let's build and design to just function".👩‍🔬 A fast internet connection (WiFi, WLAN or mobile internet) is required for the operation of the app and therefore of the robot: no internet, no use of the Pongbot!📶 In order to browse / check / edit / program a drill, you need to be physically near the powered robot🚽 AND have a live internet connection — not very convenient at all. The Nova S Pro cannot produce balls (cerves or non-cerves, doesn't matter) that are short AND have a significant amount of spin, e.g. it cannot produce short spinny cerves or short high quality pushes. Nor can it produce fast spinny topspins or actually slow spinny loops. Placing the Nova well back from the table can remedy this limitation to some extent. As long as it doesn't die on you, you woht think twice that you overpaid for a cheap, mass-produced toy-quality(!) robot because you definitely benefit from its functionality.
In summary, due to the 2-wheels system, the robot cannot produce slow balls with MUCH underspin (so-called high quality pushes). it cannot produce fast balls with MUCH topspin (so-called hard topspins). it cannot produce slow balls with MUCH topspin (so-called slow spinny loops). but it can produce fast balls with MUCH underspin (so-called balls to the moon). Other than that, the Nova S Pro performs flawlessly and to the reviewer's personal satisfaction. However, I will not recommend it until after eight years of regular operation (since 2024), by which time it will have proved its long-term value. I had opened the robot and what my engineering eye saw didn't instill me with much confidence. See the forum post for further review comments.

Personally, I think you're just too good for the robot (no glaze). Probably should've gotten like an Amicus then if you have this many grievances on the functions and capabilities of the robot
Mercury 2 Soft weight difference
Pros
  • very best performance-price ratio, very best value
  • with 43.0±1.8g cut installed weight very light!
  • high tack, extreme control, super enjoyable
  • best-selling 3$ inexpensive from world-famous Yinhe brand
Cons
  • no tensor effect, no catapult, i.e. slow shots with slow hands
77.5g DONIC blade + 2x Mercury II (old) = 159.9g (incl. Yinhe glue)
62.4g SANWEI blade + 2x Mercury II (new) = 152.0g (incl. German glue)

The above 2 fully assembled rackets include different glues plus edge tape, so the below numbers contain these components too:

41.2g is the average assembled weight of one installed Mercury II Soft rubber, cherry-picked light samples.
44.8g is the average assembled weight of one installed Mercury II Soft rubber, cherry-picked heavy samples.

In other words, if i had cherry-picked lighter production units, my racket would be lighter by 7.2g, this is good to know. On the flipside, heavier sheets mean that they are thicker, delivering a better performance. That's exactly why i paired my lighter blade with heavier sheets, and my heavier blade with lighter sheets. Because in the end we not only want the lightest racket but also a beautiful ALL+/OFF- performer. The thicker the sheet, the more beautiful its performance.

Yes, the Mercury II Soft is a slow rubber, with absolutely no catapult, no tensor effect but i compensate this similar to badminton, namely with a snappy fast racket movement thx to the light weight. For learners, consolidating coordination and shot variations, it's the perfect rubber, highly enjoyable.

Nobody ever claimed that this rubber one of the best club-level quality rubbers, but so many on the internets do claim that it has the highest performance-price ratio that mankind has seen (y). For 3$, it's the very best rubber you could buy (best value).

Highly recommended for learners, beginners, in their club and league play.

Uncut sheet with protective film and its mini sticker , taken out of the retail packaging for weighing. Mercury 2 Soft. The weight for 1 sheet can be 57.xx g or 64.xx g, while most units will be at 60.xx g. Best advice is to keep ordering 2 units at different times of the year whenever you doht know what else to order for the 10$ min cart value alix free shipping. By now I've got a collection of 12 units ever ordered. It then makes sense to pair sheets of the same weight, i.e. 57g black 57g red vs. 64g black 64g red. And more typically 60g black 60g red. So yeah, the sponge thickness can vary by 7g, if you got only 2 units.
