Would buy again

No issues

Different # on product part. I'm hoping it is still correct part to fit.

First order experience was great. Received the day after I ordered. I ordered the very same item on Jul 21st, got a shipping notification and tracking number but the item appears to be stalled somewhere. I need it sooner rather than later. I have spoken with customer service via telephone call and online chat, but not getting much of a response from either. Appreciate someone looking into it as I need this item quickly. Thanks, Tim.

Great price, in stock!! Can&#039;t beat that!

All good
