Better Bottle is a name known in the home beer and winemaking for their quality products.  Plastic PET carboys are much safer than glass carboys; not only because they weigh less, but they will also not explode into shrapnel if dropped!  These are made from Virgin PET and manufactured in such a way that the molecules are tightly packed, and less susceptible to oxygen transfer, resulting in better wine and beer!

Aside from it's advantages over glass carboys, the Better Bottle is relatively impermeable to oxygen.  This means that for your wine's or beer destined for aging, this is a perfect choice for an aging vessel!  When using the Better Bottle and it's accessories, the transfer rate of oxygen is lower than that suggested for Micro-oxygenation, and insignificant when compared to the amount of oxygen transferred through other bottles and their stoppers.

Winemakers storing wine for long periods should use the optional Better Bottle PET closures available for this product. You will be interested to read the technical, but very informative .pdf attached this product in the documents tab.

These will not last under frequent use
I've had two 5 Gal Better Bottles in rotation, in almost constant use. Even taking care not to use hot water, PBW or any caustics to clean, and setting them carefully on a towel (no concrete or rough surfaces), both of them still managed to deteriorate sufficiently to crack along the bottom and leak.
If you're an occasional user, I guess they're worth the money if you don't want to lug glass, but I brew weekly - they just don't stand up to the use.

Great Fermenter
I have three of these bottles and love them. They are super lightweight, impermeable and easy to clean and handle. You can't use brushes with these or they scratch inside. Luckily, they are somewhat resistant to stuff sticking in them vs glass, but they can get gunky with aggressive fermentations. To clean out, I shove a small rag inside and add a cup of cleaning solution (PBW, etc) then, swirl/agitate the rag around inside to clean off any residue. Turn it upside down and pull out the rag with your index finger.

The one gripe about them is the size of the 6 gal. Its too small to use as a primary if you want to use the 5 gal as a secondary. In order to be able to use the 5 gal as a secondary, you want to fill it to the neck to minimize headspace. This means you need to start the 6 gal primary with 5.5 + gal in order to have enough to rack off into the secondary. This leaves inadequate headspace in the 6 gal primary for most fermentations. Because of this, I stopped doing secondary fermentations in the 5 gal better bottle and now use purged kegs instead.

Would recommend over glass.

works great
Much lighter than glass and easier to move around. Be careful not to scratch it while cleaning, also when moving it when it's full it can suck the sanitizer from your air lock into your brew
