Value for Money8 sources11/20
How it's scored

Value = capability points earned (of 67 possible — the sum of the 10 capability categories below) ÷ the complete-system price, expressed per $1,000, on a fixed published scale: ≥30 per $1k → 20 pts · 25–29 → 17 · 20–24 → 14 · 15–19 → 11 · 12–14 → 8 · 9–11 → 5 · 6–8 → 3 · under 6 → 1 · no documented price → 0. The scale is fixed, so a score never shifts when other machines change.

This machine

Capability points = Ease of Use 4 + Max Diameter 10 + Bend Angle 7 + Stress/Materials 4 + Dies 5 + Upgrades 2 + Mandrel 0 + S-Bend 0 + Single-Source 2 + Warranty 2 = 36 of 67. 36 ÷ $2212 complete-system price = 16.3 capability points per $1,000 → 11/20 on our fixed value scale.

Ease of Use & Setup7 sources4/10
How it's scored

Two parts, capped at 10. PORTABILITY (0–3): rolling as standard = 3 · portable with a rolling option = 2 · portable = 1 · fixed/bolt-down = 0. EVIDENCE CHECKLIST (0–7): +1 each for a downloadable manual, on-machine operating instructions, a built-in bend-angle reference, published springback/overbend help (a specific overbend number OR a written measure-and-compensate method — not a vague 'expect springback'), a real rotation aid (clamp-on analog/digital or chuck/indexer — a magnet-on-tube or none scores 0), a documented quick-die-change aid, and official YouTube content for this exact model.

This machine

Portability: 0/3. Evidence checklist: 4/7. Manual=Yes, On-machine instructions=No, Angle reference=Yes, Springback guidance=No, Rotation aid=none, Quick die change=Yes, Mfr YouTube model content=Yes.

Max Diameter Capability1 source10/10
How it's scored

Largest round-tube OD the machine runs with catalog tooling, on fixed tiers: ≥2.5" = 10 · ≥2.375" = 9 · ≥2.25" = 8 · ≥2.0" = 7 · ≥1.75" = 5 · ≥1.5" = 3 · any smaller documented size = 2 · no published OD = 0. (CLR is shown for reference but not scored.)

This machine

Fixed OD tiers. OD=2.5 in. CLR is display-only (not scored).

Bend Angle Capability1 source7/9
How it's scored

Maximum published bend angle, on fixed tiers: ≥190° = 9 · ≥180° = 7 · ≥120° = 4 · any smaller documented angle = 2 · no published angle = 0.

This machine

Fixed angle tiers (≥190°=9, ≥180°=7, ≥120°=4, >0°=2). Angle=180° → 7/9.

Stress Capacity & Materials1 source4/10
How it's scored

Two parts, capped at 10; if no wall spec for 1.75" OD DOM is published the WHOLE category is 0 (no inferring strength). WALL THICKNESS (0–6): ≥0.875" (solid bar) = 6 · ≥0.250" = 5 · ≥0.188" = 4 · ≥0.156" = 3 · ≥0.120" = 2 · ≥0.095" = 1. MATERIALS (0–4): count of documented materials from steel, stainless, 4130, aluminum, titanium, copper, brass — 7 = 4 · 5–6 = 3 · 3–4 = 2 · 1–2 = 1 · 0 = 0.

This machine

0.134" published max wall for 1.75" OD DOM. Documented materials (4/7): steel, stainless, 4130, aluminum.

Die Selection & Shapes1 source5/8
How it's scored

+1 point for each die family the maker documents for this frame (8 max): round tube, pipe, square tube, EMT, metric round, metric square, plastic/urethane pressure dies, and any other clearly documented shape.

This machine

Documented die coverage for: round tube, pipe, square tube, metric round, metric square/rectangular. Points are awarded only for die families the bender manufacturer explicitly documents as compatible for this frame, including any clearly claimed third-party die ecosystems.

Track Record (Years in Business)1 source3/3
How it's scored

Documented years the brand has operated: ≥25 yrs = 3 · ≥10 = 2 · >0 = 1 · no founding date published = 0.

Upgrade Path & Modularity8 sources2/8
How it's scored

+1 point for each documented, factory-supported upgrade (8 max): power upgrade path, length/back stop, rotation indexing, angle measurement, auto-stop, thick-wall tooling, thin-wall/quality tooling, and wiper-die support.

This machine

Documented upgrade path covering: power upgrade path, built-in or machine-mounted angle readout.

Mandrel Compatibility1 source0/4
How it's scored

Documented mandrel support for this specific frame: bronze/nickel-class system = 4 · economy (plastic/aluminum/steel) mandrel = 2 · none or not documented = 0. No guessing.

This machine

Mandrel tier is explicitly none (or not documented clearly enough to score). This category scores 0.

Sources
True S-Bend Capability1 source0/3
How it's scored

A true S-bend — two opposite-direction bends with ≤0.125" straight (tangent) between them, proven by specs, photos, or repeatable test pieces: yes = 3 · otherwise (or marketing 'S-bends' with inches of straight) = 0.

This machine

No published/entered S-bend capability data for this frame; this category scores 0 rather than guessing.

Sources
USA Manufacturing Claimno source yet0/2
How it's scored

Scores the maker's own origin CLAIM only (not verified origin): a flat, FTC-unqualified "Made in USA" = 2 · a qualified/loose claim ("assembled in USA", "American made", or "Made in USA" with imported parts disclosed) = 1 · no USA claim = 0.

This machine

No published USA-origin claim (imported, foreign, or silent); this category scores 0.

Sources

No source recorded for this category yet.

Origin Disclosureno source yet0/8
How it's scored

+1 per major component whose specific origin the maker documents — USA or imported both count (we reward disclosure, not country): frame +2, dies/tooling +2, hydraulic/power unit +2, pump/motor +1, controls/electronics +1 (8 max). A part the machine doesn't have (e.g. no hydraulics on a manual bender) isn't counted against it.

This machine

No component-level origin documentation published; this category scores 0. We reward disclosing where major parts come from, not any particular country.

Sources

No source recorded for this category yet.

Single-Source System1 source2/2
How it's scored

Can a normal buyer get a complete, working system — frame + dies + the required power/lever — from one primary manufacturer/storefront? Yes = 2 · anything requiring you to source a major part elsewhere = 0.

This machine

Complete, fully functional system (frame + dies + hydraulics/lever) available from one primary manufacturer/storefront.

Sources
Warranty (Published Terms Only)1 source2/3
How it's scored

Strength of the published written warranty only: strong/lifetime on the frame or ≥3-yr comprehensive = 3 · a clear 1–2-yr warranty = 2 · a short or heavily limited but documented warranty = 1 · none, as-is, or not mentioned = 0.

This machine

Clear written warranty with roughly 1–2 years of coverage on the machine or major components. This category is based strictly on published terms; we do not score how well the warranty is honored in practice.
