The Lead Foot LFD-10 is a decent pedal for the price. If you're looking for a lightweight pedal to throw in your backpack or use occasionally at home, it certainly does the trick. It's not the most robust construction - so wouldn't necessarily recommend it as a pedal to rely upon for frequent performances. If you slam your foot on it a little too enthusiastically while performing, it WILL eventually break.
That said, it's a very inexpensive pedal. Considering what it costs, I think the somewhat lower quality is an acceptable compromise.
One other small dissatisfaction is that there is not an enormous distance between the pedal being pressed fully and released, and the spring holding it open is not especially strong. Because of this, it is not always immediately apparent solely by feel whether the pedal is pressed or not. By contrast, other pedals which have a wider range of movement or a stronger spring to push back against your foot allow you to feel immediately if they're pressed.
I use it as a backup pedal to use temporarily if any of my other pedals happen to break.
In summary, it's perfectly fine for the price. If you're using it heavily, I would invest in something with a bit more physical feedback and more sturdy construction.
