Has anyone tried the Sun ZY-203?

I saw that bestofferbuy.com has the light going for $3.50 with free shipping. Most other places seem to have the light going for $12-20. Has anyone used this light or other lights by the same brand? If so, should I expect a $3.50 light, or have I found a deal?

it's worth 5.00$ maximum

It's a chinese emitter like a powerlight or a blf Delight,horrible tint ,terrible threads, bad light.

Don't waste your money .You won't be impressed .

Yes, you are completely right this is not good for your requirements and you would not get the expected performance.
