Llego muy rápido, sin embargo, tiene pésima calidad. Mal armado y aún falta ver si está correctamente calibrado.

Es una perdida de dinero. No sirve para nada. Lo probe con diferentes perros y a manera de entrenamiento y y al cotrario de controlarlos, cada vez que se activaba, ladraban aun mas. BASURA

I purchased several of these for use in my Physics classroom as we've been studying force and I needed a few more scales. Metric spring scales are a good way to measure newtons. I wanted to do the lab in a few days; I wish that I had read the delivery times more carefully as these took at least 5 weeks. The scales seem to be accurate but they production is of very low quality. The metal face plate is stamped metal and does not seem to have been filed or finished on the edges (eg. they are sharp... not ideal for working with students who tend to fuss with equipment. Bleeding cuts are not a good thing in a Science classroom!). The calibration is made by sliding the *face plate* up and down rather than adjusting a screw which is more typical for this type of measuring device.

después de unos meses de probarlo sigue sin ser efectivo, el perro ladra y ladra sin cesar ya que es un chihuahua infernalmente desquiciado; no es ultra frecuencia ya que si se escucha el sonido que emite, lo use como indicaba el instructivo y nada más no funciona; no gasten su dinero en esto no vale la pena.
