Easy to find correct part

All good

The casing on the speaker was broken, but I did have another casing to use. You only had one available, and I couldn't find it anywhere else, so I chose not to return it.

New to thmotorsports and hope to do more buisness with them

Great shopping experience!

Just great

Finding the item was great. There were not many places that had it due to stock shortages from Onan/Cummins. The price was a lot lower than the closest company that stocked it. Ordering was easy. However, I contacted CS due to the fact that the "Tracking" link in the email did not lead me to any type of tracking. The only thing it did was go to the invoice for the order. I was kind of bugged as I was getting ready to head out of town and needed the part. I do web app design and implementation for a living. Someone needs to check the click on links to ensure they go to the proper place.

Great prices and fast shipping!

Best company ever
