Great, well built,I’m loving the extended reach model and it’s still able to get in those tighter areas. There has been a few times when the light will get blocked because the extended reach will get in those type of places. All in all very good product.

Great ratchet! Easy to get into tight spaces, the battery last a long time and powerful enough for most jobs. With the manual ratchet ability, you can snug bolts after the tolls capacity is exceeded.

Awesome tool! So fast compared to brushed Milwaukee 1/4 ratchet. Although the torque is insane, it is easy to control with the lever and I have not over-torqued a fastener yet (have mainly used it to zip up 1/4" aircraft engine bolts before torquing with torque wrench). Battery consumption is also very reasonable, I love this tool!

Use this tool daily . Very strong and durable. I bought this one to use will my four year old Fuel rachet is being repaired. Milwaukee replaced my old one with the new series. I would recommend it to anyone needing reliabe tools.
Works great. Small head gets into tight spaces. I use my heavy duty 3/8” for the tough jobs. Under dash work is where it really shines!
Picked up this ratchet because I already had the extended reach 3/8 and wanted something a little more compact. This ratchet is very comfortable and balanced in the hand and wicked fast. This is a must have for engine and interior work
I have used Milwaukee 1/4 ratchets since they have came out. My lively hood depends upon them. The Original Fuel was a terrific step up from the Original ratchet. This new high speed fuel ratchet however, is quite the disappointment. Sacrificing torque in order to obtain a higher speed is unacceptable. I honestly didn’t think a loss of 5 would be so bad but, it is. It also chews through batteries much faster, and the lever lock is touchy. I don’t think I inadvertently flipped the lever lock on any of my other M12’s, but it happens at least once a day with this one. Sounds small but, it’s pretty aggravating when your holding a body panel in place with one hand and you have everything all set to go just to find out the lever is locked. The faster speed and the fact ... MoreI have used Milwaukee 1/4 ratchets since they have came out. My lively hood depends upon them.

The faster speed and the fact that it says Milwaukee on it are the only reasons why this didn’t get one star. This is a step in the wrong direction. Luckily, I was able to find 2 Fuels, and I’m able to trade the unopened high speed I bought for on of them.
Out of all the 1/4" drive battery operated ratchets I have used the Milwaukee line has to be the best on the market, Smooth action, tons of torque that you would expect more in a 3/8" drive not a 1/4" drive. Great speed control at the lever arm. The design, strength and tolerance of the mechanical components that are designed into this ratchet is nothing short of incredible. And yet this ratchet is very light weight compared to the competitors brands. My next purchase is the 1/4" long reach ratchet which I look forward to adding to my tool arsenal. The batteries have a great capacity by size and charge extremely quickly time and time again. I have yet to replace the battery in any of my Milwaukee tools. The oldest battery that is used daily and is over 5 years old. ... MoreOut of all the 1/4" drive battery operated ratchets I have used the Milwaukee line has to be the best on the market, Smooth action, tons of torque that you would expect more in a 3/8" drive not a 1/4" drive.

Small, light, very quick. Does have less power in reverse than the extended fuel 1/4 but not by much, maybe 5-10 ft lbs. MILWAUKEE IS Awesome, BUT PLEASE MAKE A LINE OF AUTO MECHSNICS TOOLS IN LIME GREEN, we all grew up with the craftsmen red tool boxes so most of us hate red. MUCH LOVE AND RESPECT for the Milwaukee product, brand, and red and white line, next is Milwaukee lime green and white line of ratchets and automotive impact wrenches!!!!!!!!!!!
I’m glad I finally got this. I wanted to get one for a while. Not sure why I waited this long. Great time saver, easy to use, and battery is awesome like all my other Milwaukee tools.
