Great. Use for Noopept nasal solution. No locking mechanism though.
Great product! The only reason I hesitated to give 5 stars is that it doesn't have a locking mechanism. Consequently, when you put the cap on, if you don't obstruct the mechanism from going down, it will let off a wasted spray. Otherwise this product is perfect. I use it to make a Noopept nasal solution with 1% alcohol solution. Works amazingly.
Rating: 4 stars
