Flum and RAZ are two of the most popular disposable vape brands we sell at VapesOnlineShop — and they take fundamentally different approaches. RAZ dominates on per-device flavor depth (50+ options on a single device) and wide retail availability. Flum leads on hardware innovation (the only dual-flavor switching system on the market) and aggressive pricing ($24.99 for 50K puffs vs RAZ's $27-29). This comparison puts them head-to-head across every dimension that matters.

| VOS Brand Rating | 8.4/10 | 8.7/10 | RAZ (barely) |
Final tally: RAZ wins 6 categories, Flum wins 4. But the categories are not weighted equally — if price and innovation matter most to you, Flum's wins carry more weight. If flavor selection and convenience matter more, RAZ takes it.
Flagship Face-Off: Flum UT 50K vs RAZ VUE 50K
This is the matchup most users care about — the 50,000-puff flagships from each brand.
| Spec | Flum UT Bar Pro 50K | RAZ VUE 50K |
|---|---|---|
| Puffs | 50,000 | 50,000 |
| Dual Flavor Switch | ✅ A / B / Mix | — |

| VOS Price | $24.99 | ~$27-29 |
| Mix Mode | ✅ Blend two flavors | — |
| VOS Device Rating | 9.0/10 | 8.8/10 |
The Flum UT 50K wins on price ($2-4 cheaper), innovation (dual-flavor + Mix Mode), and our device rating. The RAZ VUE 50K wins on flavor count (50+ vs 40), screen quality (3D vs HD), and brand recognition. Both are excellent devices — the choice comes down to whether you value the dual-flavor system or maximum single-device variety.

Price & Value — Flum Wins This Round
| Tier | Flum Device | VOS Price | RAZ Equivalent | VOS Price | Flum Savings |
|---|---|---|---|---|---|
| 50K Flagship | UT 50K / Mello Pro 50K | $24.99 | RAZ VUE 50K | ~$27-29 | ~$2-4 (8-15%) |
| 25K Mid-Range | UT 25K | $23.99 | RAZ DC 25K | ~$24-26 | ~$0-2 (similar) |
| 20K Entry | Mello 20K | $22.99 | RAZ TN9000 | ~$18-20 | RAZ cheaper here |
Flum's pricing advantage is strongest at the 50K tier — the segment where both brands put their flagships. In the entry tier (9K-20K), RAZ's TN9000 is actually cheaper, but it offers fewer puffs. For full pricing analysis: Flum Price Guide.
Availability & Buying Experience
This is RAZ's clearest advantage. RAZ has broader retail distribution through gas stations, smoke shops, and vape stores nationwide. Flum's retail presence is more limited, concentrated in independent vape shops primarily in the Southeast US.
For online purchasing, both brands are fully stocked at VapesOnlineShop with identical shipping terms (Memphis, TN warehouse, 3-5 business day delivery, free over $80). The local availability gap only matters if you need a device today and cannot wait for delivery. More details: Flum availability guide.

Frequently Asked Questions
Is Flum or RAZ better overall?
RAZ has a slightly higher VOS brand rating (8.7 vs 8.4), mainly due to broader flavor selection and wider retail availability. However, Flum wins on price (10-15% cheaper at 50K tier) and innovation (dual-flavor switching is unique to Flum). The "better" brand depends entirely on your priorities.

Many popular flavors overlap — Blue Razz Ice, Watermelon Ice, Cool Mint, Mango, Strawberry, and Grape are available from both brands.
