most of the professional clarinetist marker says a good wooden clarinet life span is 15 years if taken care properly.for yours,i think it definately sounds great.but for intonation wise,maybe abit out of tune for some notes.

ps.tosca is not a toy for market.its great.the french saleperson which was a former french marine clarinet brought for me to try to test out the response of the market.it blows and feels like opus.but even BETTEr~
