While Savox USA provides excellent customer service when products are under warranty, I have been burned without any after-warranty support when I fried a servo due to a faulty BEC sending full 4S power to the servo. I requested an RMA to get the servo repaired but they refused to give me an RMA without buying another servo first, they told me to send in the receipt with the bad servo and then they would replace it under the warranty for the new servo. This whole deal seemed shady, but I complied with their demand and roughly 6 weeks after I shipped them my RMA, they sent the bad servo back and denied my warranty claim because I didn't purchase from an authorized distributor in the USA. I went round and round several times with the Savox USA rep over the phone how they never said anything about where I needed to buy the servo from, things started getting nasty when I asked them to help me contact Savox Global because my request from Global for an RMA went nowhere. I felt that I was left high and dry with no support and was tricked into buying a second servo.

This would be the last Savox product I would purchase.

Lessons Learned:
1) Be sure to pay more and verify you buy from an authorized channel if you want support
2) Read the fine print before you make a purchase, most brands of servos will not warranty stripped gears and won't offer any service after warranty has expired.
3) Don't trust anything anyone tells you over the phone, they will not stand behind their word and give ambiguous instructions.

After this experience, I have tried many other brands of servos, some will at least sell you a refurbished servo if they can't repair it, had this happen with Radiopost once.

Before selecting your next brand of servo, I would visit their customer support page on their website... look for some sort of replacement fee schedule for any kind of service repair work outside of warranty... otherwise expect your servo to be disposable when the warranty expires.
