It took some getting used to for me to get the technique down for using this, but I had messed up several coaxial connectors using a cheaper tool. Once you know what you're doing with this tool, you'll almost never foul up a connector. I highly recommend this - and an additional pack of connectors at first to "practice" on!
PROS: Really the only way to go for coax installation cheaper tools just don't cut it
CONS: Takes some getting used to, and maybe some pliers to open once in a while
Let me say that while I can crimp CAT5e/CAT6 cables in my sleep, I'm a total novice when it comes to coaxial cable. If this describes you, don't get this tool. I got it to go with PID 9910 and I never got it to work. It jammed shut and I destroyed the BNC connector getting it back open the first try. I tried again and it bent both ends of the BNC connector and refused to unlock/unlatch. The packaging is labeled "Compassion Tool" instead of "Compression Tool", and the instructions with it aren't much better.
If you're already a pro with BNC connectors and RG-59 cable, and you need a solid tool, this is probably for you. If you're a novice to coaxial cable and have a one-time job, get something else.
PROS: Solid feel and construction, probably very durable
CONS: Not for beginners instructions aren't translated to English all that well
