Redragon K673 Pro Review — A Tom's-Guide-Praised $60 Tri-Mode 75% That Replaces Most Premium Boards

The Redragon K673 Pro is what Redragon's product strategy looks like when it works. Three years of revisions on the same form factor — wireless 75% with knob and gasket mount — and the current generation is good enough that Tom's Guide's reviewer headlined their piece "You don't need any other keyboard for less than $70." That's the kind of positive press headline budget Chinese boards almost never get from mainstream tech media.

I have Tom's Guide (title and search-summary specs — full body fetch was blocked behind the paywall), MacSources' 90%-scored long-form review, Bryan Thinks' first-hand owner review, four substantive r/BudgetKeebs threads (including reviews from u/badmark, who runs a respected budget-keyboard YouTube channel), and two YouTube reviews. Coverage is strong for a budget product — better than the K580 VATA, much better than the F2088.

What you're actually getting

Tri-mode wireless gasket-mount 75% with a knob, pre-lubed switches, 3000mAh battery — all at $52-65 street. MacSources reviewer Jon Walters called the price "more than fair and provided more features than I expected." (review) Bryan Thinks went further: "Given its quality, features, and price, it's an absolute steal!" (review)

Gasket mount that actually changes the feel. Per the Tom's Guide search summary: "The gasketing makes the keyboard feel like a keyboard three times more expensive from my interactions with this unit." Bryan Thinks confirms the typing experience: "The K673 Pro is super quiet to type on, offering a crisp and soft typing experience that I absolutely love." That's not a typical budget-keyboard description — gasket-mount boards usually start at $120+.

Knob, dedicated wireless modes, real battery. Per Bryan Thinks: "The keyboard comes with Tri-Mode technology, which allows you to connect it using a wired USB-C connection or wirelessly through a 2.4GHz connection or Bluetooth." And on the chassis: "The keyboard has a satisfying weight to it – it doesn't feel cheap or overly light." MacSources on battery: "The K673 has a built in 3000mAh battery. For a keyboard this size, it should last close to two weeks. In my experience, depending on usage I got a week to ten days using full RGB."

How it actually performs in owners' hands

The pattern across r/BudgetKeebs is "this is a serious budget option, not a toy." u/badmark's original K673 Ucal Pro review thread (7 upvotes — small but from a known reviewer) drew genuine engagement. u/Slicer021: "Awesome review as always. Was kinda bummed when I saw they didn't put the nicer switches like in the K631 Pro SE." badmark replied: "Thanks! Yes, that surprised me as well, but have given them feedback and marketing says they intend to update that!" The community sees the K673 line as worth iterating on.

The mod ceiling is clear and not low. From u/badmark's mod stack on the same thread: "Modded: Redragon K673 - 1x Tempest Tape, PE Foam, 'PET' Mod (Ziploc) / Tecsee Blue Balloon linear (S) / GMKY Vior WOB DS ABS." That's a mid-tier mod stack on a sub-$60 board, and the resulting sound test is what convinces people the platform is worth buying into.

The Ucal Max revision adds hot-swap and the community noticed. From the K673 Ucal Max thread, u/the_supreme_crumbus: "XDA profile key caps and Gateron yellow switches. It's been a great keyboard so far." The Max revision is the K673 line for buyers who want to swap switches; the base Pro is the K673 line for buyers who want it to just work.

The MacSources reviewer brought their teen son into the test: "He enjoyed the key bounce/feel and the portability of the keyboard." That's the K673 Pro at its best — genuinely usable across an age range and skill level.

Where it falls short

The K673 vs K673 Max distinction is binding. Per u/badmark's Max thread, hot-swap is a Max-revision feature. The product MDX flags the base K673 Pro as non-hot-swap, and the listings on Amazon are not always clear which version they're shipping. Before you buy, check the listing photos for the explicit "hot-swap" callout — if it's not there, you're getting the soldered version.

Stock switches are utilitarian, not exciting. u/Slicer021's complaint quoted above is the canonical one — the K631 Pro SE shipped with better switches than the K673 line. The Pro and Max both work fine but neither is a sound-test darling out of the box. Most happy K673 owners either accept this or budget $30 for switches and (if they bought a Max) swap them.

Naming is a mess. K673 / K673 Pro / Ucal Pro / K673 Max / K673 Ucal Max are all terms for the same product line across revisions. Redragon's marketing names overlap with retail-listing names which overlap with brand-shop names. The MacSources reviewer slipped and called it "K6783" once, which captures the confusion. The Reddit hobbyists know which name maps to which generation; the average Amazon shopper won't.

The 1000Hz polling rate is fine, not exceptional. u/badmark confirmed the K673 line uses standard 1000Hz polling on USB and 2.4G. Newer competitors at the same price (some Aula models, some Ajazz models) hit 4000Hz or 8000Hz polling. For office work, irrelevant. For competitive shooters, a real difference.

The entry-level market discussion is correct that this whole category is confusing. The 23-upvote discussion thread on the entry-level mechanical market is itself the meta-evidence — buyers at this tier struggle to tell the K673 / Aula / Ajazz / GMK67 / RK boards apart, and the K673 doesn't have a viral hook to break out from the pack the way the Aula F75 did.

Should you buy it?

Buy if you want a no-drama tri-mode wireless 75% with a knob and gasket mount for around $60, you're going to use it as-is or with light mods, and you want mainstream-press validation that you bought a sensible keyboard (Tom's Guide, MacSources at 90%, owner reviewers all aligned). For a generic "I want a good keyboard for the office without thinking about it too much" use case, the K673 Pro is hard to beat.

Skip if you specifically want hot-swap (buy the K673 Max revision instead, or a hot-swap board like the GMK67), if you want a polling rate above 1000Hz for competitive gaming, or if you want a switch profile interesting enough to be its own talking point (the Aula F75 Pro's Leobog Reaper switches win on sound).

Wait if you're cross-shopping with the Aula F75 Pro at the same price — the F75's gasket mount is more aggressive (5-layer foam stack), the switches are more thocky, and the QC is more variable. Pick on which trade-off you want, not on price.
