What our customers think

"We have been working with the staff at PTI for approximately 10 years. In that time we have found them to be extremely responsive to our needs, both for technical expertise and for supplying products to help us get to market on time. They are very easy to work with, and always accessible when we need advice or technical information, and their technical expertise and attention to detail are unsurpassed."

"PTI has been making battery packs for us for over 10 years.  We have a great relationship with PTI and their support is excellent.  PTI has gone the extra mile for us many times.  Should a problem arise, they are right on it and it gets resolved quickly.  It has been a pleasure to work with them.  I wish I had a few more vendors like PTI that are this easy to deal with."
