Customer Letters
Thank you very much for taking the time to meet with Antonio and me yesterday,it was great to see the GM Battery facility and talk with you,And thank you so much for a wonderful dinner!
Antonio and I are very interested in the samll batteries you produce to incorporate them into our jewelry.
You suggested we contact you about available sizes of batteries,and that maybe an engineer could send us a document that outlines the size and capacity tradeoffs.
Again,thank you very much,and have a great week,I look forward to further discussion with you!
