    I purchased this product for my ex-wife who lives in a different state. However, she told me that it arrived in excellent condition. The dog leash was as advertised on the website: brand new, unused, and still in the manufacturer packaging. The shipping speed was very fast. The appearance of the product was very good. It works well and seems to be an excellent value for the price paid. This seller did a super job in shipping the item quickly! Would purchase from them again. Thanks very much!!

    Great test kit

    Have used this same kit for years. Accurate and daddy. Although one of the droppers in the bottle was damaged I was able to replace dropper with the old one from a empty bottle I had. This is a good kit.

  • Exactly What I needed

    Everything works as it should, HOWEVER, the ammonia solution has spilled inside and damaged the color card and the inside too. That's my only issue, other than that everything was good. Seemed the box was bounced around or something.
