several years ago I bought a Maruyama weed eater,23 CC and I have yet to use full throttle.
starts on or before the third pull every time,what makes this one special is the torque rise,much faster than anything in its class.
it cuts cleaner and faster than any brand I have ever used and I have used a lot of them.
light weight,easy on the back and non of that dreadful hand numbing vibration.
one thing to remember,the size of line you use can turn a good weed eater into a great weed eater regardless of brand.
smaller line cuts faster and takes less HP/amps hr to cut.
