Buyers Beware--Evo JET TURBINES has ripped me off for thousands of dollars. After I sent them money in advance for multiple engines, they have failed to send me my engines or given me a refund. This has been going infer over 3 months. They have given me excuse after excuse and now refuse to answer phone calls and emails. Are they having financial problems? I would be careful if you do business with them and be careful when sending them money. You may not receive your engines or any refund.
