SDI Diagnostics 29-7000 Mouthpieces for Peak Flow Meter / Spirometer, Disposable 100/Box

Excellent t

This was a refill for device and picture shows it clearly. I was expecting the device.

It is exactly as described.

The picture clearly shows the peak flow meter and should not be in the picture at all!Also Amazon needs to show that this is returned frequently higher up otherwise I would not have purchased this it would have alerted me that this is IN FACTNOT A PEAK FLOW METERCAUTION:DO NOT PURCHASE IF YOU ARE WANTING A PEAK FLOW METERThese only go on the mouthpiece very disappointing

I thought this was the peak flow meter. It wasn’t. Cardboard mouthpiece. Return itbut only got $35 back on my $50 purchase. The picture of what you’re actually buying is misleading

Not the product.

Liked that I could finally use my breath meter again. My old plastic one finally gave out after years of use.They are now made of thin cardboard, and therefore wear out. So instead of a single, washable/reusable mouthpiece, you have to buy this jumbo bag of replacements. They work but are not eco friendly.
