aircraft electrician / mechanic here. I've had 3 pliers from different manufacturers in the last two years and they all broke. They cost between $40 and $100. I don't use "famous tools" unless it is necessary. The price is outrageous in my opinion. Either way, they're comfortable, reversible, and work great. The only thing I like is the better grip with the bolt locking back. Maybe some rubber. If your hands are greasy, handling the lock can be painful. Regardless, I intend to buy from Ares again after living with the pair for at least two years.
