Again, some people complaining about $150 price tag comparing to savox. Guess what... My savox SB2284 (2 of them) and SB2283 are $140 servos. I didn't pay that for them but in comparison they are in the same price range. I am willing to try the Tekin low profile servo o my EB410. Looks like a very nice quality servo. If they make spare gear sets available that would be even better.
