    Great transaction, seller was very communicative and ensured I was ordering the correct parts for the vehicle I was ordering parts for. Parts were packaged well and protected well for ship.

    This rating is for purchase, cust service and description/condition of items. Arrived in a very timely manner, I had a few questions for the seller prior to purchase that they answered entirely and likewise fast. Packaging was very solid and protective (expandable foam insert) so it appears they addressed previous feedback in this regard. Everything that was advertised was included, and in perfect new condition. Will update after installation and a bit of use. So far A+++ experience!! WDDBA!!

    Product as described except for the hose clamps. Ordered 2, only one shipped. Contacted seller no return communication. But did end up sending missing item in a timely manor. Add shows 3 high-strength t-bolt clamps, both orders had the smaller clamp being ordinary hose clamps.
