    Not high end... but not with the high end price tag. Works excellent. Easy to install and adjust. Highly recommend for a retro upgrade. Bought two of these over the past several months. Consistent and fast shifts up and down always. But Using quality Jagwire shift Cables is part of that equation.
    One I used with a 6 speed Freewheel. No issue. The other on a 7 speed Freehub/cassette. Excellent buy. This is typically found as OE on $600-$1100 road bikes. Not Walmart/Target bikes, etc. This is a short /med cage for 11-28 Road bike gears. Just make sure the Chain is at the correct length. Often overlooked. But makes the biggest impact on shifting if too long or too short. Some OE bike setups even have the chain too long in general. By maybe 2 links. My observation from experience. YouTube for a an adequate explanation fo this. There are many vids to learn from. Park Tools has one of the best youtube vids. on Derailleur, cable and chain installations. Start there if you are new to this. But it is truly a DIY project if you are comfortable with tools.

    I replaced a different brand one on my Chinese made Schwinn. Easy enough to install. watch a video on youtube to see what the adjustment screws on the unit do to fine tune it. So far, it works perfectly on my 7 speed bike.

    I used to be a daily commuter until this derailleur flipped into my spokes and put my bike out of commission. It wasn’t the derailleur’s fault—I had been messing with the limit screws and barrel adjuster without knowing what I was doing.

    After about two months, I finally replaced the derailleur with this one, put a new cable through, and it works like a charm. It was easy to install, and the screws and adjuster seem to be correctly set. Hopefully doesn’t happen again. It was the same derailleur that came with my bike, so I decided to get the same one to minimize any confusion on my end. Not a top of the line derailleur, but it gets the job done on my 7 speed.
