Compared To
vs Chicco KeyFit 35

vs Graco SnugRide
Graco seats are often lighter and cheaper, but Willow S has better crash test results and ARB.
Source Threads
Concern over ClickTight wiggle and base movement
User reports side-to-side wiggle at the ClickTight end of the base. Community consensus: some movement near the seat bight is normal; the install is tight if the base doesn't slide easily. The ClickTight indicator being green doesn't guarantee zero movement. The seat is safe as long as the base doesn't shift more than 1 inch at the belt path.

Help with harness adjustment and rethreading on Willow SC
User struggles with harness rethreading on Britax Willow SC (similar to Willow S). CPS tech explains step-by-step: straps must be removed from splitter plate and reinserted at correct height. Reminder: do it early as baby grows; infant insert only usable up to 11 lbs. Also discusses recline angle and fit for small newborn.

First-time dad concerned about base wiggle
New parent notes minor wiggle after ClickTight install. Reassured by community: slight movement is normal; check for less than 1 inch of movement at belt path. The base is secure, and the anti-rebound bar adds safety. Suggestion to try re-installing if wiggle excessive.
