Oi Vey.... how many ya got Tim..??
Like the others have said... if you spend a bunch of time on them, they can be made to work; soles need flattening, frog beds need refining, mouths need de-flashing etc... none of it rocket science... but IMHO it should all be done before it leaves the factory...
FWIW.... I've hears an argument that provided you use them on the material they're <using the term VERY loosely> "designed" for... they should be fine... as evidenced by countless carpenters and joiners... apparently softwoods is their preferred media... I know from bitter experience that hardwoods tax them beyond their limits.
Handles supplied with em will trash your hands with prolonged use, but as Tony has demonstrated, suitable replacements can be made or bought if you're so inclined.
They do have advantages.. strange though it may seem, those soft blades will accelerate your learning curve when it comes to sharpening. Any mistakes can be polished out and re-done quite easily. The blades themselves can be swapped out for after-market upgrades with a corresponding increase in performance...
If you stick with em for a while, they'll teach you one of the most important lessons.. how to read grain direction.. they'll let ya know in no uncertain terms when you're doin something wrong... trust me...
I wouldn't say they're a write off... but given the chance I woulda steered you in the proper direction loooooooong before you had a bunch of em....
Welcome Aboard...
