Does a tennis racket need to be restrung when you buy it?

Pre-strung rackets in this pool ship playable, but multiple expert and retailer comments — including tennis-warehouse.com's listing notes on the Speed S and midwestracquetsports.com — specifically call out factory strings as the weakest link and recommend a restring with a synthetic gut or poly after the strings soften. Reviewers generally suggest restringing every few months of regular play regardless of whether the strings have broken.
