At the price there's not much to lose really but I wouldn't expect a great sound. You really need a clip on condenser mic I would have though but they can get very expensive and need external power.
You might be better with a cheap lapel microphone although you'd have to check they are not too sensitive.
If you can get a cheap magnetic soundhole pickup on there somehow, that might work best (although realist you probably have not got a soundhole!)
