Sorry,nope
isn't it a bit costly? the can is not refillable right?
I've seen these being used at some laptop repair shops. The shopkeeper told me the price to be around Rs. 200, although those bottles were pretty small.
I have not used them because I wasn't too sure how they work - should be good as long as you use small amounts.
use silica gel to free the moisture content.
That small white packet coming in shoe boxes right?
