Awesome vendor, super fast shippng and the lowest prices anywhere. Highly recommend and will use again.

I ordered parts expecting my in stock items to be delivered promptly. Had a few issues there. The logistics need to be updated. I was contacted about the mistakes made and was justly compensated. I appreciate the second effort and will give them another try.

I have searched for this part all day I called and the people on the phone were very polite. If they have this part and ship it fairly quickly I will definitely be using this company in the future.
