A great company to deal with. Ann is very knowledgeable and helpful.

I requested help in choosing a 16-port rotary union for a complex industrial application. The customer support and technical assistance were excellent.They followed up with a call or two to check on the status of the order, but it was not intrusive.Also, the lead time for delivery is on the order of two weeks, which in my business is great.After receiving the equipment, I realized I had forgotten to order an accessory. I was able to resolve this quickly with customer support and had it ordered and delivered quickly.I would definitely recommend DSTI to engineers or designers.Thanks DSTI

Awesome product and super fast shipping! The only downside is electrical slip rings are non returnable, even if they are unused. Makes it kind of important to get the right size the first time.

Excellent customer service. They are always open to our ideas, willing to work with us on any of our needs and meet our expectations in a timely manner.

DSTI is always helpful, timely in response, professional in communication, is more than simple order fulfillment and advises when a better fit for your application is available and the cost of this package is competitive for similar products! An all around value!

DSTI has terrific technical support and great products. I purchase a 2 conductor rotary union that exceeded expectations.

Good products, they have worked flawlessly for our company every time
