I have the tools now tried the same. The price performance ratio. One can not expect a professional tool for this price. For everyday and especially for everyday use certainly not intended. Who even a battery, or shortened occasionally at his clock, the watch strap or sometime extended again - really helpful. For the truly wide watchbands as for my thick "Invicta" Watch XL - unfortunately suited only limited. Since the strap can not be clamped to shorten the belt.
