I loved Rivendell. And, I mostly like the Home Alone kit. However, the lights for the plumbing van hook to a lithium battery (not included). Once hooked up, I have to press a little button. The lights flash inconsistently. The Battery compartment looks like it is supposed to have an on/off toggle. It does not and seems like a cheap (or broken) aspect to this kit. I wrote to the company, but got no response. I would have preferred the plumbing van to just hook directly to the house lights (like the tree house).
