Yours too?? I bought one. CS 303T, as an emergency fill in for my Stihl 193T. I have not managed to get any use out of it. Fires right up in the morning, runs/cuts well (when it warms up which takes a quit a bit of cutting before it finally leans out). Shut it down to pile brush, pick it up and can't even get a "pop" out of it. Multiple trips back to dealer who can find no problem with it.
No, I have an SRM222 trimmer for the garden. No point using the big Shindaiwa for it as I try to keep the garden in somewhat of a decent shape.
I've bought it new because Echo and Shindaiwa here are always running promotions on their Made in China offerings and needed something light for the garden.
Besides the fact most of the steel on it is already rusting, I've had big issues with the standard trimmer heads these small cheap units come with. This year Yamabiko probably got tired of my constant nagging "It's still under warranty and the trimmer head exploded again" and they have been handing out Made in Japan Sugihara trimmer heads as warranty replacements. It's probably worth more than the rest of the trimmer itself.
It has also become harder and harder to start when cold, which I blame on the cheap crappy ZAMA carburetor suffering from even more premature aging than me.
I've decided to keep this thing until it blows up or stops working. Apart from carburetors (China copies are less than the genuine membrane kit), spare parts are prohibitively expensive, as is typical with Echo and Shindaiwa. The ignition module alone is over one third of what Yamabiko is selling these small trimmers for now. So I won't fix it and just buy something else.
