First, I would like to let you know that I'm aware of a few topics already made regarding "try" here:
But after reading those topics, I still feel unsure, therefore I write this question...
This is about when you go to Japanese Electronic Store or something similar, and you want to buy the appliance (in this case a hair straightener). Before you pick the item and go home, you want to make sure that it functions well... So we'd like to say "Can I test it?" (to see if it's not broken)
I come up with a few sentences... But I'm unsure if these are correct...
ためしてください (I want to test it)
ためしてみたい、いいですか？ (I want to try testing it, is it okay?)
使ってみたい、いいですか？(I want to try using it, is it okay?)
It's written in dictionary that ためして is to test, but I read in some comments that ためして is very rarely used in common daily life. And when it's used, it's being used for something serious like to test a new government law or something... Is this right?
Could you help to explain what is the best sentence to use in daily life for this situation? Thank you so much in advance :)
