Worth it
Circa 1860s house with circa 1980/1990s windows. We ordered 14 inserts for entire home, and they made major impact on drafts and overall temperature control. Had fit issue due to one quirky window frame, and company sent replacement TWICE until it was right. Fantastic customer service, seriously.
Got the standard inserts, not the noise-dampening ones, and while not the primary goal, have certainly noticed significant difference in outside sound reduction, as well.
Not cheap, but waaaaaay cheaper than 14 new windows in an inflated market with some questionable workmanship right now, too.
