Value for Money

Autoscaled mechanics-only value using rawValue=(capabilityPoints/entryPrice). capabilityPoints=23, entryPrice=735, rawValue=3.129e-2. Dataset band: P10=3.363e-7, P90=2.460e-6. Values are clamped into [P10,P90] and mapped to 1..20.

20/20

Ease of Use & Setup

Portability: 0/3. Evidence checklist: 1/7. Manual=No, On-machine instructions=No, Angle reference=Yes, Angle stop=No, Rotation aid=none, Quick die change=No, Mfr YouTube model content=No.

1/10

Max Diameter & CLR Capability

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

10/10

Bend Angle Capability

Fixed angle tiers. Angle=180 deg.

7/9

Stress Capacity & Materials

No published max wall thickness for 1.75" OD DOM; this category is scored as 0 rather than guessing.

0/10

Die Selection & Shapes

No published/entered die-family coverage for this frame; this category scores 0 rather than guessing.

0/8

Track Record (Years in Business)

No published/entered years-in-business value; this category scores 0 rather than guessing from brand.

0/3

Upgrade Path & Modularity

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

1/8

Mandrel Compatibility

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

0/4

S-Bend Capability

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

0/3

USA Manufacturing (Disclosure-Based)

Disclosure-based tier 5/5 based solely on the manufacturer's own claims about where frames, dies, hydraulics, and assembly occur. We do not audit factories or offer legal opinions on FTC compliance; this scores the stated claim only.

5/5

Origin Transparency

No meaningful origin disclosure in published/entered data (or only vague/marketing language); this category scores 0 rather than guessing.

0/5

Single-Source System

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

2/2

Warranty (Published Terms Only)

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.

2/3

Brand: JMR Manufacturing
Model: TBM-250R
Country of manufacture (claimed): FTC-unqualified (unqualified means not-claiming exceptions or pretending to be something it's not) "Made in USA"
