I originally purchased the Robic M-357 Tally Counter. After purchasing it found d it was shipped on a slow boat from China. Took 4 weeks to get to me. I needed it faster so I purchased the S.P. Richards counter, which I received in 3 days. After using the two counter side by side, the Richards is better. The push button on the Richards registers at about a 3/4 length of the push on the plunger. The Robic needs to be pushed all the way down, making it easy to miss a count. Richards brand seem to be sturdier, and has a larger wire that forms the finger piece in the top, the Robic is thinner and probably weaker.
