This extension is A game-changer for industrial drilling. The 18-inch length allows for increased versatility and reach while the durable construction holds up to tough jobs. The quick-release feature makes for easy changes and adjustments. The only downside is the price point, but the quality justifies the cost .Overall, a must-have for any industrial and scientific drilling applications..
I can only give four stars because luckily I didn't have to use all the functions. But I can say that it is of high quality. The universal phone jack works on my iPhone 6. And it seems to be doing everything it's supposed to. Again, I didn't have a chance to test all the features.
