It may well be rubbish I'm sorry to say.
Basically with Loki rubbers, in my experience the only ones worth buying are those that are sold as a rubber sheet only ie: WITHOUT a blade attached. These are their proper competition rubbers, made with premium materials, and are usually an excellent product.
Those cheaper rubbish rubbers have the same LARC as the good ones, because they came from the same rubber mold.
This is how Loki and other manufacturers are able to do multiple variants on the same rubber. The sponge and top-sheet material changes, but the rubber mold remains the same, and it only has the same LARC number, because that number is engraved into the rubber mold... but it's very much a garbage-in / garbage-out process.
If you pour top quality rubber into a rubber mold, then attach the resulting topsheet to top quality table tennis sponge, you''re going to get a decent playing rubber.
If however you use rubber with the consistency of dried camel snot, then strap it to a used kitchen sponge...
...Well, let's just say the end result won't be attracting any famous player's signatures in a hurry 🤣🤣
I had a bit of time to play this racket now and I give a little update.
Please do not take this as a serious review it is just my personal experience.
These are the reasons why I bought it, basically because it is one horny looking unit. 😁
Other reasons are:
I never owned a blade with Koto, only Limba or other softer veneers.
I wanted to find out what I will get when I buy Rxton5 rubbers with blue and black sponges.
This is the review I left at Aliexpress:
""""There is no criticism of the seller, communications were friendly and they are quick to reply. The shipping was fast and I am perfectly happy with the shop. The racket as the pictures and the description is concerned is the usual "sales Gimmick . This combo does not work at all. Considering that the blade is carbon / Koto , with the rubbers supplied it is shockingly hard work. The black rubber can be used on another blade and made to work well. The blade shows potential when fitted with proper Rxton5. The red rubber is like a soggy cardboard and reminds me of a short-pimples-out rubber with 1mm sponge."""
I do honestly not know why the combo , as advertised does not work, it felt gutless , there was simply no power in it.
I also do not have the slightest idea why the blade feels great and is fast with good control after I fitted regular Rxton5.
The black rubber with the black sponge is of good quality and fitted to one of my ZLC blades works a treat.
The red rubber has a very tight sponge but the top-sheet is of a completely different composition
than the ori Rxton 5 and is very soft and thin. I managed to hit some explosive BH flat hits that reminded me of Mima Ito 😇
I am still quite happy with my purchase .
