kits are a good way to start into building pedals, though don't expect it to work without LOTS of troubleshooting. just like with programming, you often spend most of the time debugging a circuit until you get it to work. especially with increasing number of components and pots.
for somebody who's just starting, i'd strongly recommend starting by building a simple boost (super hard on, for example) or an AB switcher.
beware that kits are also mostly pricey and often won't be much cheaper than buying the cloned pedal used.
