I am looking for professional grade hair clippers, any suggestions? - professional clippers

I cut the hair of my son and my husband's hair with clippers, the couple have recently purchased an Oster. This is a lower model. We have Easter in the past and seems to do well, and after a while. The one we have now cut off during use and difficult to operate, we had less than a year, and the road is boring. Suggestions would be very grateful!
