FIRSTINFO F3220DD Manual Torque Multiplier 600 Nm with 3.4:1 Gear Ratio and 1/2 Inch Drive Adapter for Lug Nut Removal and Heavy Duty Wheel Work

Feels solid, works as expected, quickly shipped. Weakest design that L-shape stopper seems quite clumsy.

Well made but didn't have a chance to use it due to the design and its use on my Porsche centre-lock wheel nuts. The arm wasn't long enough but I suspect it would work for other items.

used it to remove some very stubborn leaf spring bolts where i couldn't get a pipe on the end of a breaker bar due to access did one side without this and spent 3 hours just to get one bolt out, with this it took 10 minutes on the other side

The torque multiplier is a great item and very useful, not just for wheel nuts. It’s quite weighty and seems well made. It operates entirely as intended and makes short work of wheel nuts put on by idiots with pneumatic impact guns. Why not 5 stars? The restraint bar is hardened steel but it’s sloppy. As it’s so thin, it tends to ride up that which it is hard up against and with steel wheels with small holes, it’s too fat to fit in the holes and properly stop the rotation meaning it cants the multiplier over. The restraint plate needs to be thicker around the body of the multiplier and the end of the restraint bar needs to be able to fit in smaller gaps, over other wheel nuts or extend to the floor

Ok

Very compact, works exactly as well as others costing a lot more.Good value for money

Simple to use and easily strong enough to torque up a hub nut on a Land Rover Discovery. I thought I’d only use it for that but it’s helped to loosen some seriously tight fixings.

product is as good as one three times the price

très bien

Important first note, I only used this to torque a nut to 500 ft/lbs so I didn't push it to its claimed limit. This worked perfectly for me and was incredibly less expensive than a torque wrench with the same capability would have been. The multiplier has a range of accuracy of something like 4% which has to be figured along with the accuracy of the torque wrench you're using as well. This could result in a relatively large variance in actual torque applied but that's the payoff for saving a couple hundred dollars (minimum) on a higher capacity torque wrench.

支える所が曲がるので力が掛からず逃げる 中心の遊星歯車機構はそれなりですが、数万する商品と比べるとお遊びにもならない 大人しく大トルクのインパクトレンチ買った方が幸せになれる

I haven’t used this yet, but appears to be really good quality

Bought this to use at work in a heavy equipment technician environment. Works great in areas where you need big wrenches torque spec but access barely allows full size wrenches to fit Update on 03/20/2025 well it worked great but after a year the output shaft broke off, will have to buy the bugger one next time
