I love the products, the only concern i have is that i placed an order, i got the order and stuff was missing. I contacted them and they made it right with me. They even gave me extra covers for free to make it right. Thank you Curien!!!

Eric, thanks so much for taking my call. I’m terribly sorry that we missed your extra lead set. As discussed, we provided you free units in your last shipment for the slight shipping delay and will include some extra goodies for you in this next one as well. Thanks again for your time and help and I wish you a great day!

Tried contacting this site by phone, email and chat with no response. Had to file a dispute and a report to the FBI IC3 complaint, Product was available at Amazon for $100 less. These are in limited quantity and no longer available according to an Ebay seller. Company took the time once they found out about this situation that was unfortunately overlooked to make it right and they have. I am now very happy with their service and support.

Gary, sorry to hear you had such a bad experience. We admit that getting ahold of us by phone is difficult, with well over 100 spam calls per day we had to almost all together stop answering the phone. We have plenty of stock and amazon sales are sometimes available. We have reduced the ability of others to resell the products due to violations of MAP policies and other support concerns. We have Tooldom as our trusted reseller on ebay and amazon as well as a select few others. I see that you have an order with us that went unfulfilled and will reach out to contact you from that information. Again sorry you had a hard time getting ahold of us. - Joshua Carton

I won't bore everyone with the technical details but suffice to say Josh from Curien dealt with my issue promptly and professionally and got me back up and running quickly. A superb tool with a superb company behind it.

Loving the products, the fuse order came in yesterday. I was wondering about some test leads I saw on a video, couldn’t find them on your website.
