Understand the collection before booking
The presentation describes W1 as flexible assistance, W2 as sports assistance, W3 as low-profile assistance and W3M as the Mom edition. These labels help frame questions; age or gender alone does not determine which model suits a person.
Compare weight and fit
The stated weights are 3 kg, 2.2 kg, 1.75 kg and 1.65 kg respectively. Verify the version, battery and accessory definition, fit range and adjustment method. Weight is only one comparison point; actual fit must be assessed separately.
Ask questions around real use
For everyday use, ask about wearing, controls and gait adaptation. For outdoor use, ask about modes, battery conditions and environmental limits. Follow the manual for the specific model and on-site guidance.
Verify new models rather than copying old specifications
W2QQ and W1PRO are also listed. Their confirmed images and specifications have not yet been supplied, so W2 or W1 data is not reused. Confirm the exact model, version and available trial location before comparing.
