Score breakdown

Value for Money

Features-per-dollar scoring based on 15.0 points earned in the other categories (out of 80 possible feature points) and an estimated minimum safe operating system cost of about $10001250.

0/20

Ease of Use & Setup

Unknown power type operation with JMR Manufacturing ergonomics (base score 7/11) and portability tier: fixed base / no portability data (+0 pts).

7/11

Max Diameter & CLR Capability

2" OD maximum round tube capacity based on published specs. Math today is OD-only; CLR ranges will be added to the score once consistent CLR data is available for all machines.

7/10

Bend Angle Capability

No published bend angle

0/9

Wall Thickness Capability

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

0/9

Die Selection & Shapes

No documented tube/pipe die families beyond basic or unspecified coverage.

0/8

Track Record (Years in Business)

Proven track record, but not as long-standing as the oldest brands.

1/3

Upgrade Path & Modularity

No documented upgrade path beyond the base configuration for power, LRA control, or bend-quality tooling.

0/8

Mandrel Compatibility

No documented mandrel capability for this frame.

0/4

S-Bend Capability

No documented ability to form back-to-back opposite bends with ≤0.125" tangent; marketing "S-bend" claims with several inches of straight between bends do not qualify.

0/3

USA Manufacturing (Disclosure-Based)

No disclosed USA manufacturing claims, clearly imported origin, or only very weak USA-flavored language.

0/5

Origin Transparency

No meaningful origin disclosure, or only vague/marketing language without concrete component origin details.

0/5

Single-Source System

One or more required components must be sourced elsewhere, or the manufacturer does not clearly offer a complete system from a single source.

0/2

Warranty (Published Terms Only)

No meaningful written warranty, sold as-is, or warranty not mentioned in published documentation. This category is based strictly on published terms; we do not score how well the warranty is honored in practice.

0/3
