No luck with the Power Sharp System for my MS290... Gonna give it a go this weekend.
Thank you for your interest in the Power Sharp™ system.
Power Sharp is only available at this time in the 3/8 low profile type chain. As the MS290 takes the 3/8 standard or .325 pitch chains, Power Sharp is not yet available for this saw.
