Nope! You can reserve as many tools as you like. However, we simply ask you to reserve and borrow what you need. Monopolizing all our circular saws or routers is not cool. We're all about sharing stuff, after all!
Suppose you are organizing an event and you need a lot of circular saws, drills, accessories, ladders etc etc. That means we need a lot of time to prepare the order during our opening hours.
What's more, it's possible and even likely that a few items still need to come back that day, because other people forgot to bring back tools in time, or due to some other exception.
In principle, you don't need extra insurance. However, for really big projects involving plenty of people using the tools, it might be a good idea to search for an external insurance.
It stands to reason: the tools you borrow, and the more people are involved, the greater the odds that something bad happens.
