IR ThunderGun Impact Wrenches any opinions?

How long have IR stuff been made in China? I was looking at an new 1/2" air ratchet wrench and was surprised to see the made in China label.

ive noticed the IR air tools sold at tractor supply and most of the ones sold in stores we all made in china.....the ones sold off the snap on truck were made in japan....which my guess would be a better unit..??
