Had an older model 10 plus years old that finally died. Lots of hunting for options and we came right back to the Lathem. My only complaint is that it not the last one we had can’t quite line up and print vertically on the card exactly between the lines. Does not effect use, just bugs me, lol. Getting it set the way you want is a bit challenging at first, but manageable. Love the atomic clock feature!

I spoke to a very kind sales associate of yours. He was very pleasant and I told him I truly do like Latham’s products. I have used your time clocks and time cards and ink refills for many years now, and I will continue to do business with your company. I have referred many people to try your products, as I know many small business owners in our area. “THANK YOU LATHEM FOR YOUR KINDNESS, SUPPORT WITH ANY ISSUES THAT ARISE, AND THANK YOU FOR YOUR GREAT PRODUCTS!” ...From a very satisfied customer! 😉

I had an issue with the Lathem time cards that I purchased. I called the company and told them. Within a few days they replaced the defective time cards with new working cards. Problems can happen at any company, a good company knows what to do to fix it and Lathem sure did!

One of the only time clocks that gives a cumulative total as the employee clocks out. We use it for weekly required study hours on the university level for our athletes. Working great!

Our old time clock finally gave up the ghost. This unit was almost the same model as the one we replaced with the added function of the automatic time setting from the Atomic time. It is working like a charm and we are back on track.
