Fantastic tool for the price.
Great tool to keep! I travel for work and this little key tool has been a life saver multiple times. Customers often lose their cabinet keys and its nice to have my own so im not wasting my customers time trying to find a key to open a cabinet to troubleshoot. I have gifted several of these to friends, coworkers and customers because they find it just as useful as i do.

Fits old radiator
Works exactly as needed/expected. I live in a house they expect was build around 1910. We have radiator heaters and, as one does, have long since lost the key. I have carefully used pliers in the past but worried we would damage them so I ordered this to try to bleed them. Came on time, I was initially discouraged because none of the arms fit, but the center was a perfect fit. We were able to safely bleed all radiators without damaging them in just a few minutes each.

Don't give up on this key and try all sides
A condo owner in my building kept sending me emails about bleeding baseboard heaters. I ignored it at first because I just didn't want to mess with two of three of my baseboard heaters that work well. But the third one leaves much to be desired, and I have been using my electric fireplace and wearing hoodies because it's so cold in one room. I gave in and bought one of these things after seeing his instructions for bleeding baseboard heaters. I watched a zillion more videos so I wouldn't mess up when I did it. Then, I get this key and none of the four edges work. I sighed and got ready to ask for a refund when I noticed one more key in the middle. I already laid a towel down and a bucket because of how the videos looked. I tried that last one in the middle expecting nothing to happen, and immediately all this black gunk kept pouring out. Then, the black gunk turned into water. My eyes lit up immediately. I wish I knew this seven years ago when I first bought this place. I'm hoping this makes the "cold room" considerably better.

Ladies love the Zumunda BLING.
Mr. Zumunda gets the ladies. I wear this on a necklace when I go to the bingo club to do my hustle. I win big every time acting old and senile. People give me props and say I look gangster. Yeah, you know it. All blinged out. No idea what it is, but if the ladies like it, I'm hip.

The product is not as shown in product page. It is different and material isn’t steel alloy but appears to be magnesium. Finishing is poor. Center of the tool doesn’t have hexagon key but it’s round
