What reviewers say

Three verified owners rated this servo 5/5. Two reviewers praised fast shipping and value for the price. Reviewers disagree on packaging: one found the servos loose in the box with inadequate air-pack protection, while another said the items arrived well packaged. One reviewer had not yet used the servo, so no performance feedback is available. The third review mainly praises the seller's service rather than the product itself.

  • + Fast shipping
  • + Good value for the price
  • + Seller service praised
  • − Packaging criticised as inadequate by one reviewer
  • − No performance feedback yet
