(+) The PLUS:
+ Easily attaches to a bench, a table, or even a vertical support thanks to its great versatility
+ Allows control (and adjust with key ad hoc radius, not supplied) the veil using two sensors adjustable and protected by a plastic cap (avoids scratching the painted wheels, such as the rims dedicated to brake disk and thus without shoe exclusively for track). Wheel jump of control is done using an adjustable flap.
Price + content, especially when compared with professional products, nearly 6 times higher or more.
+ Foldable, lightweight, space-saving when not will use that.
(-) The LESS:
- There is no adjustment to the width of the hub. So use the flexibility of the amounts, twist and firmly screw the wheel.
- Lack of clear overall rigidity, which translates small movements of the wheel just by rotating it by hand. This interferes with the veil of the rim and makes the tedious and annoying adjustments.
- The probes are almost contiguous to the amounts I have preferred the more forward, where it intervenes with the spoke wrench. Another advantage of professional products.
- The characteristics speak of a manufacturer compatibility from 16 to 28 inches. What about the 29 inches? I have not tested, so I have one reservation on this diameter.
Conclusion: cheap product but lacking rigidity.
