It's large and weighs a lot (hence 4 stars) but other wise a very nice mount.
Quality is very good/well made. Not brittle but I have not crashed with them yet! - The only way to really test strength. Value is there. Looks fairly neat. If you need an extended mount then this is a good choice.Purchased these to replace my older 680 mountings. Great improvement, much neater to wire , moves the motor out by around 5mm and very easy to fit /adjust.
Dont consider just buy you won't regret it.
