Needs chest strap

8 months ago
Its ok but only has a waste strap which makes it feel a little bit unsecure and harder to use the pump becaue of it. It works but it needs an additional chest strap.

Waste of money

11 months ago
I purchased this product and it only last about 3 months if that long before it stop spraying. I had so much trouble with it. It is not worth the money. I spent about $100 or more on this product and it was a waste of my money. It is sad that these kind of products are sold in the store. I am on a fix income. I have not be able to purchase another kind.

No, I do not recommend this product.
