dfk41 during 2020-2022, Lelit managed to release Elizabeth v3, Bianca v3, and shortly after Mara X v2, each with noticeable new features. the lockdown was only affecting manufacturers in early months of 2020 but then things were adapted, especially within R&D.
the situation is same for all manufacturers, it’s only if they want/need to innovate. I think problem with ECM/Profitec is that they are already popular in prosumer market, their main lines (500/600/700 and Synkronika etc.) are still selling very well, and if a customer upgrades they will likely go for another segment entirely (LM/Decent/Slayer etc.), so they don’t think they need to introduce new things/new features.
