Features:

.What's  Ringbom Stirling Engine?
Ringbom engine is a unique Gamma-type engine. the displacer of a Ringbom Stirling is not driven by a mechanical linkage, but by gas pressure variations forces on a displacer piston rod within the engine because the piston is connected to a crankshaft. The Ringbom Stirling cycle engine is unique in that there is no mechanical connection to the displacer.  The engine has only four moving parts.
The Ringbom engine concept published in 1907 has no rotary mechanism or linkage for the displacer. Ringbom engines and the plans are very rare but now you can build a Ringbom engine of your own!

.Vertical modelling is delicate and beautiful, cabinet and exquisite
.Reliable quality, piston and cold cylinder are made of metal, strong and durable; the heating head is quartz tube, which will not break under the instantaneous high temperature or cooling.
.Exquisitely made, the parts are precision machined by CNC machine tools, with superior performance and easy disassembly
.The surface has a bright color and smooth feel
.Model are equipped with alcohol lamps, and a heating head and two wick
.Simple and convenient to operate, when you got it, It takes just a little bit of alcohol to get it going, either as an experimental textbook or as a gift
.By using this product, children can understand the starting principle of vertical Stirling engine, improve their hands-on ability, and deepen their interest in physics in the process of experiment.
.When not being used, it can also be placed in the home as furnishings.
.Suitble for people over 8 years old

Great oral probiotic!
Size: 30 Count (Pack of 1)
Great oral probiotic! Tastes very good and has the right strains for oral health. Brushing, flossing and scraping are all key... and adding in a good oral probiotic is like the icing on the cake. Not too expensive either. If you are looking for a product like this, I can highly recommend NatureWise.

Didn't Hurt, Didn't Help Much Either.
Size: 60 Count (Pack of 1)
Recently I was looking for an oral probiotic to help with sinus, gums and tartar for both myself and some pets. As a result, I purchased both this product and Great Oral Health's probiotics. Even though this product did have some positive effect as regards sinus pressure, it took two tables three times a day to work. Also, I noticed that an earthy, clay-like smell to breath in both myself and my pets as a result of using them. It didn't cause any harm, only that it was slightly disconcerting to smell like dirt. The product from Great Oral Health didn't take as long to produce results, and there was a visible reduction in tartar. Also, no odor. All in all, nothing majorly wrong with the product, except that it doesn't have results noticeable enough to warrant buying again.

Same probiotic strains, but a subtle formulation update
Size: 60 Count (Pack of 1)
I’ve used NatureWise Oral Health Probiotics (WiseBiotics) for a while and recently noticed a clear difference between the older and newer version — especially in taste and texture. After comparing the labels side-by-side, there has been a formulation change. The probiotic strains are still the same (including BLIS K12 and M18), but the newer version now lists Organic Inulin (90 mg) as an active ingredient instead of just a minor “other ingredient.” This seems to explain the changes I noticed: • The tablets feel more powdery/chalky • The taste is slightly different (a bit less crisp mint, slightly sweeter/fiber-like) • The dissolve/chew experience is not quite the same as before Inulin is a prebiotic fiber, so this change may actually help feed the probiotics — which is a positive. But it definitely changes the user experience. For me, it’s not necessarily a dealbreaker, but it’s noticeable enough that others should be aware, especially if you’re sensitive to texture or ingredients like inulin. Bottom line: Same probiotic strains, but a subtle formulation update that affects taste and texture. Still a good product — just not identical to the previous version. Hope this helps someone else who thought they were imagining things 🙂

These WORK!
Size: 60 Count (Pack of 1)
I purchased these two bottles ago for help with dealing with a bad case of oral thrush caused by a couple rounds of powerful antibiotics and fluconazole (rebound?) for a bad UTI and resulting yeast infection. Oil pulling, mouthwashes, salt water rinses all helped, but this put me over the top. I also take a candida killing herbal supplement as well as a variety of probiotics. I appreciate the mint is very mild (these are NOT breath mints which only mask the problem) and dissolve them slowly in my mouth at bedtime along with another during the day. I am also sure to not put anything else in my mouth for a good long time after so the pb’s can do their magic. i believe the thrush is mostly gone, but I still have some residual tingling and burning from time to time. These, along with good oral cleansing practices, help tremendously. I now order them regularly. They also make your breath fresh, naturally. Great product. Highly recommend!

Taste
Size: 30 Count (Pack of 1)
I ordered this a week ago, and it seems to taste like smoke or an ashtray. It was not a pleasant taste at all, I expected it to be great with all the other good reviews. Unfortunately that was not the case for me.
