Romsons Respirometer Respiratory Exerciser, Multicolor

Good for breathing. Good quality. I ordered one more now.

Respirometer is best for lung exercise. Ramson respirometer is a small, handy and light weight product for day to day lung exercise. You can also count and increase your breathing power by regular use of this product.Best for asthmatic patient....It is made up of hard plastic material.... Having small lengthy flexible pipe....But no problem with that...One more thing.....!It is far better to smoke this respirometer than smoking a ceggret...

Good product 😊👍

Not functioning as we expected. Ball not lifting in all time even for right inhale or exhale. Design fault.

Dear Amazon users .Requesting all of you to check the brand of your spirometer .Romsons spirometer are accurately designed with respect to size of orifice at each cylinder along with appropriate sized balls. This is very important when considering spirometer from rehabilitation point of view. Not only I use it personally, I help people try romson spirometer and see the difference themselves. May you all have a intense and throttling respiratory health !

It is good n essential for everyone n everytime n more particularly in this pandemic days when lungs get affected first n that make oxygen saturation down in the blood leading to death , so one needs to monitor it regularly for keeping oxygen adequate either from external source or other alternate measure to avoid death. So this oximeter is cheap n handy to use.

If we buy outside cost is 700 but in Amazon for same quality 200 only. Good product. Cheap and best

I ordered two pieces,side of the chamber in one of the pieces was found broken Rest is ok make sure that packing should protect the productThere was no cushioned packing which is required for fragile material like plastic
