Low price, works great, but not the best materials
I bought this for a low-budget 10-speed build to put on an indoor trainer, so weight wasn't an issue to me. The R43M is mostly steel and plastic, which is how they keep the price down. Because of this it's much heavier than a 10 speed Shimano 105 5700 derailleur. However, it is compatible with 10-speed Shimano 105 5700 shifters, which is awesome. It is NOT compatible with Tiagra 4700 10-speed shifters, because Tiagra uses the 11-speed pull ratio, so if you're trying to replace part of your Tiagra system keep that in mind.In order to keep it from being too heavy, they made one of the derailleur frame parts and the jockey wheels out of plastic. I totally get that this is a cheap derailleur, but it doesn't feel like good glass-infused polymer, just normal ABS plastic. I'm not very confident that the plastic jockey wheels are going to last long, but luckily you can buy aluminum jockey wheels on Amazon for $10 or so. As for the plastic derailleur frame, I guess we'll just have to see.Does not come with any instructions, but you can find them on Microshift's website and it's a very simple install. The steel is well-made and sturdy, the bolts are high quality, and it doesn't look as cheap as it is once you put it on a bike. Shifts very smoothly with Shimano shifters.Overall, it's great for the price, but Microshift can't expect to get 5-stars when they're bringing stuff like plastic jockey wheels to the table.

Bargain derailleur
I converted a drop bar bike to straight. These work well with ths MTB style shifter. Not the lightest, but they seem durable.
