After much research and consideration, I realized I needed a good hydrometer and test tube. I researched the available ones and this is the one I settled on. It was a good decision. This is glass, not plastic. It is transparent and not frozen. I can read the results. It has a little blue hickey so you can't break it easily. My only regret is that the purchase cost three dollars more than you can buy now. Come on, buy this item. This is the best offer. for a really good set. You really need this article.
