Masterclass is mainly gold in colour lar... this long time already not recommended...

That depends on which shop you buy from. The last batch I bought was terrible - each shuttlecock could only last at least 1 match. However, the latest batch which I got from Elin Collection was quite good, as it made till 2 matches, and some even longer.

If you want a better one from Protech though, get the Platinum one (black tube, inside a box) - slightly more expensive than Masterclass (last I saw from Elin it's about RM 62 per tube), but worth it. One word of caution though.... this shuttle can fly VERY FAR, so don't overhit your clears or lobs.

Should be Protech Masterpiece..I think.

I read  in a forum in badmintoncentral maybe 6 years back, I remember 1 guy mentioned that when got complaint, Protech will change the shuttles  to good one..when no complaint..they will change back to less superior one. Not sure how true it is, but on and off in forum you will notice that Protech shuttle quality sometimes can be very good sometimes can be  bad, it depends on your luck.

I would suggest that you go for other brands for the time being until Protech changes back to good one after they see your complaint here.

recent masterpeice no good. no no.
few stroke already kembang...
