Texas Deadlift Bar

I bought the Texas deadlift bar for my husband a bit over a year ago. I did reach out to the customer service received no emails back with an issue we have with the Bar.
My husband is In strongman and powerlifting active. He is also a personal trainer for more than 10 years and knows how to use a deadlift bar. He has had several bars and he loved the bar at first. Now the bar starts over spinning and slipping out of his hands even with using straps. He deadlifts more than 700lb and huge spin is quite noticeable and throws your whole liftoff. Actually very high risk for an injury. We would like to know either how to fix it or find some sort of solution. Did research but couldn’t find anything. Of course a deadlift bar is supposed to have some spin as it’s not stiff bar but it’s to the point where it’s not normal. My husband has been since high school into powerlifting and doing strongman for awhile plus having several medals and belts and statues laying around. I mention it to make clear he is not misusing the bar and knows how to use it. I don’t understand how the customers service won’t get back to us or give any help on the problem. That bothers me the most.
It could just be a problem during manufacturing I don’t know but customer service should be there to help.
I am sure if everything goes well this is certainly a nice bar.

Bar is solid. Great knerling and well made. Shipped in one week. No defects. Great price. Excited to use it.

I'm loving the bar so far I've only used them in powerlifting meets before this. So using one weekly is rough on the hands but I like and it's nice to deadlift without a stiff bar

Exceeded my expectations, amazing product

Easy order process, fast product shipping time, packaging was secured well. The bar itself is amazing. My wife and I recently competed in a Push/Pull event and we used a Texas DL bar during the event and it felt amazing, we had to have one. Love the feel of the knurl, and the grip I can get with it. I can hook grip comfortably. I look forward to the PRs with this bar.
