Big thanks to Rob for helping with an urgent request we had on a Friday afternoon. The part we needed was in Europe, and Rob went out of his way to get it ordered and delivered to us by the following Tuesday.City Bearings
Absolutely fantastic service. Rob was very helpful. Great communication. The requested part was shipped in no time.Konrad Eliaszuk
Found the component I was looking for at a great price. Excellent support from the staff as I was paying by wire transfer. Fast delivery and very good packaging.Adriano Tiberi
Extremely helpful. They shipped me a replacement unit the next day, and I was up and running within 24 hours. A brand-new replacement from the machinery manufacturer would have had a 7-day lead time.Sean Conlin
Found the part we needed at the best price. I spoke with Rob to make sure it was actually in stock, as many companies don’t really have it available to ship. It was ready, checked, and shipped, and we received it within a few days from their German stock. Would definitely use again and recommend.Chris Sentance
Excellent service, especially from Mark, who stayed late to make sure the part arrived the same day since it was a critical component for me, even though it was my first time using Marvo. I will definitely use them again.Josh Holt
