Summary: After alot of searching and reading reviews I settled on the MP27-MG. I have had Canon calculators for years but the last one (MP25DV) I had was just ok. I wasn't sure if I was going to stay with a canon. I use the triple 0 key alot so I was happy to find this machine offered it.
Summary: I had a very old Canon calculator that finally died and forced me to shop for a new one. I do like the Canon MP27-MG but it has taken some getting use to. I am not as fast or accurate with this unit and I think it's because of the redesign.
Summary: Have used for 2 weeks, and is nice and fast, I will have to get used to the double and triple 0's on the pad. I used my previous one for 20 years. The placement of the 0 will be tough to get used to.
