Review (4/5): Love 'em!
Ilike the bottle for its proper and the glass definitely seems sturdy. They come nicely packed with a variety of extras, as described. They do leak at the neck in the sprayer (not from the bottle or collar itself). And the sprayer heads don't tighten with the collar so they spin freely. In using mine for Peroxide spray, homemade stain spray, cloth wipes water, etc and they are great for that purpose. Love having the option to use the spray nozzle or the simple cap. The caps are leak-proof!
