Outstanding value and quality
Purchased to replace the servos in an indoor Mini CrackYak. Significantly less expensive and and much better performance than the recommended items

Original servos not in stock so agreed replacements could be sent. New servos are excellent and do the job perfectly. The only issue I had was the refund for the price difference took a while to sort out. Other than that I'm very happy
