This company is fantastic! I could not have asked for better customer service. I bought a plane where the SureFly was replaced due to a mechanic saying it was bad. I asked for them to include the “bad” mag as part of the sale. After one email I received a call within hours from the SureFly service department. I sent the SIM back as instructed. These guys knocked it out of the park. They rebuilt the mag, included all new paperwork, and sent it back to me within a week! I could not have asked for better service from an aviation parts company. I will be doing business with them much more and will recommend them to anyone that asks. Thank you all and keep up the great work!
