Before you buy anything
A few things worth knowing first
Don't start with feather shuttlecocks. Feathers are the standard at clubs and in competition, and they do fly better — but beginners smash them out of shape after a handful of hits, at $1.50-2 per shuttle. Nylon shuttlecocks last ten times longer, fly just as well in casual play, and cost a fraction as much. Switch to feathers when your technique is consistent enough that the difference actually matters.
Yonex is the brand that actually matters in badminton. It's the one name you'll see on the bags of every serious club player, and for good reason — their entry-level rackets are genuinely better than mid-priced generic rackets in swing feel and durability. If you're spending $40+, spend it on an entry-level Yonex rather than a flashy no-name. Victor and Li-Ning are the other real brands; everything else is a step down.
If you plan to play at a gym or badminton club, don't buy a net — just show up. Clubs have courts; you only need a racket and shuttles. If backyard play is the plan, a portable net is a 10-minute setup. Either way, don't let logistics delay you — find a club first, make sure the sport clicks, then buy anything beyond a racket and some shuttles.
