I was pleasantly surprised by the incredible power it has in relation to its size, as well as its ergonomics.
With the proper technique, it can cut even thicker wood beyond the ten centimeters specified. Whether dry or green, it doesn't matter for the T-Rex, it cuts just as quickly everywhere. I use it on olive trees.
Its batteries last unbelievably long, over 150 cuts for the large 4.5amp battery and over 80 cuts for the small 2.5amp battery.
I also have the Campagnola Stark L pruning shears, which use the same batteries. That was the main reason I bought it. Yes, it is expensive, but here too the saying holds true: you get what you pay for..
