El producto es de muy buena calidad y funcionó a la perfección. Se que hay otras opciones más económicas pero también son de mala calidad. Estoy mas que satisfecho con la compra... si tienen la posibilidad de adquirirlos no lo duden... solo chequen bien la medida.

Las tallas vienen mal , ni siquiera los de tamaño grande son para perros “Grandes” son demasiado chicos incluso los medianos y grandes son para perros chicos , mala descripción muy mala experiencia de compra , no los recomiendo para nadie solo a chihuahuas

Had a couple and they do tend to fail quickly - usually with false low oxygen alarm and displaying 0 % oxygen level. Impossible to then recalibrate.

La calidad de la tela y los velcros es excelente, son muy fáciles de lavar y no retienen malos olores.Lo único que diría es que son un poco pequeños, compré la talla correcta (M) según la tabla que muestran, de acuerdo a la medida de su cintura y sí le quedan, pero un poco justos.Sugiero actualizar la tabla para perros medianos y grandes, largos y delgados, etc.Creo que a mi perra le hubiera quedado mejor la talla grande y eso que es pastor belga pero muy pequeña y su cintura mide 51 cm a penas!Aún así creo que son excelentes, muy buena calidad, sólo a la siguiente compraré talla grande.

Al principio mi perrita se sentía incomoda pero ya se acostumbro. Absorbe y no se escurre. La talla le quedo perfecta.

Anteriormente tenia que limpiar mi casa todos los días varias veces, por la incontinencia de mi perrita. Desde que usa los pañales mi casa huele bien y ya no estoy ocupado limpiando todo el día. Muy recomendables, fáciles de poner, fáciles de quitar, fáciles de lavar.

I don’t have the lab equipment or know-how to evaluate this unit’s accuracy. I doubt most buyers do. But it’s reasonable to assert that it at least can detect the gasses it’s alleged to detect, and provide an alert when the concentrations become unhealthy. I have tried blowing on it, producing a low oxygen alert, which is reassuring. Farting on it does not trigger the hydrogen sulfide alert for me, but I can use my nose to detect H2S. Anyway, no calibration certificate or calibration data was provided, but it does include a little hood with air hose feeds to allow you to calibrate it yourself, if for some reason you have the equipment to do it.I’m mainly concerned about detecting carbon monoxide and propane, because I want to use this in my camper van. Mounted low, it should be able to wake us up and get us out of the camper in case of CO or propane concentration. I also am considering using it for abandoned mine exploration, but would like to use it in conjunction with a partner’s different unit until I am completely satisfied that it works for this application.The unit comes with a very nice aluminum carrying case with cut outs for the USB cable, phone-style USB charger, and the calibration hood you’ll likely never use. The case is rugged, but is much bigger than it needs to be. Do you need a rugged case for a phone charger and a USB cable? By the way, the cable is micro USB, not USB-C. The unit recharges using the phone charger, so you can top it off anywhere you can charge your phone. It also comes with a pretty detailed instruction manual, a big plus, as well as a lot of customization for alarm threshold levels.The unit itself is constructed from rather cheap feeling plastic. It’s reminiscent of a toy. But it’s not a big deal… the thing looks cheap but feels solid enough for its purpose. To be honest, smoke alarms also feel like cheap plastic, and we have no problems using those.The alarm it provides is a heavily accented feminine voice telling you exactly what the problem is, followed by a klaxon type alert. Some words are too heavily accented to understand, but you get the gist of it. There is also a dim red light that comes on as well, and an indication on the screen what the issue it. Mainly, having an unfamiliar voice telling you stuff in the middle of the night should wake you up before the klaxon even sounds.I’ll admit, I don’t have a lot of experience with these units to determine if this specific model is better or worse than all the others. But I do know that it is priced competitively, is well packaged, and appears to work as advertised. If I had paid for this, I wouldn’t be disappointed.
