Build around the Switch Flex 2.5G.
It's already in your kit below. Add a gateway and PoE and the discount starts working. Discount tiers climb with the bundle — the bars fill as you build.
Type your address. We'll spec the building.
Square footage, floors, rooms, construction type — turned into an AP count, a switch size, and a gateway that fits. No guesswork, no overbuying.
Four quick questions size the kit. Property-records autofill is in the build phase.
Enter an address and the plan appears here —
property facts first, then the kit.
Pick the right one, not the biggest one
The honest line-up from switches. Most buyers reading this page should buy the middle column.
Asked before checkout
The questions our support inbox actually gets.
Does it ship the same day?+
Orders placed before 2 PM ET on a business day leave the same day from our bench in Altamonte Springs, FL. Tracking is emailed the moment the label prints.
What if it's the wrong size for my building?+
Return it. 30 days, no restocking fee, refund to the original payment method. Better: send us your floor plan first and we'll size the kit for free — half of all returns are sizing problems.
Who handles the warranty?+
We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue overseas.
How does the bundle discount work?+
Add items to a kit in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole kit.
