The packaging seems to be very nice and professional. I like the fact that the bubble pack opens and closes giving you the option to store the system back into the original packaging. Everything is in Chinese, with a few "Engrish" words, but this is to be expected. I don't think that there is any intent on marketing this product in the US. Forget about trying to read the instructions unless you do understand Chinese. The package, reveals on the back, that the system is available in six colors.

     Upon opening, the first thing that I noticed, there is no headphone jack! It only has an Audio and Video output for TV hookup. The overall feel of the unit seems to be well built and constructed, but it does not have that solid feel to it like the GB Advance SP and GB Micro does. Thin Plastic? I like the fact that they chose to go with the white buttons rather than the silver cheap looking ones that JungleTac normally put on their systems. (They changed the button colors with the Caplet and Tablet). It has analog volume control. The volume can be turned up to a surprising level for such a tiny speaker. The screen is not recessed, which means that it can be easily scratched. Overall things are better than expected. The cartridges are a bit on the flimsy side with very thin plastic housing. The unit fits my hands as well as can be expected for medium adult hands. I am comfortable with it. It has a very nice sharp bright backlit screen. The NES "A" and "B: buttons are reversed!!? I have yet to be able to get used to this when playing Super mario. The "jump and run" are very awkward to use like this. Is this only a matter of habit of playing on the original controller?

     The carts, that contain the games, are multi-carts. Meaning that there are more than one game included on each cart. I have seen carts available with as little as 2 and some with as much as 101 games included on a single cart. The MD carts being the carts with the fewer games. There seems to be four categories of games; NES, SEGA Genesis, Gameboy, and JungleTac's own original games. An NES cart contains a miniature NES on a chip and a specific number of games. Among the NES sometimes you may find a  Gameboy game mixed in, like Donkey Kong Country 2. Try playing that through without a save feature.
     The SEGA Genesis games need the MD Converter to enable you to play them on the OneStation. The converter contains the SEGA Genesis on a chip and the individual carts contain only the games. My guess, as a reason for this, is that maybe it is a bit more expensive to produce the "SEGA on a chip." They seem to be trying to keep within a certain price point. The design, for the SEGA carts, causes the games carts to be very tiny and fragile. The thin PC board connectors, unlike the NES carts, stick out past the plastic housing leaving them unprotected and maybe easily damaged. Ironically the NES game carts come in a nice little protective plastic storage case and the MD carts, that I have found, only have a flimsy soft plastic sleeve for storage. One could store them in the original packaging, which is an open and closeable bubble pack
     The NES games seem to be mostly from early in the system's lifespan and they are the "original" NES games. A lot of the games are arcade type games, along with games like the first Super Mario, Super Contra, Jetsons, etc. The SEGA games are the "original" games but, not as many titles are available  compared to the NES. Outrun, Sonic, Tinytoon Adventures, Batman & Robin, Steel Empire, to name a few. The biggest problem with purchasing more than one cart is repeats of games. You may end up with repeats of some games that are on the previous cart that you have. Some carts have a better mix than others. This might be just personal preference though. One would be wise to study the contents of the game list on the carts before purchasing.
     The biggest thing to consider about the games is that it is retro gaming. Nothing new, just old fashion dated games. If you like the old stuff, NES, SEGA, then you are going to have fun.
     Another thing to think about is that there does not seem to be any permission from or credit given to Nintendo, or SEGA, to use or market their stuff. But then again I do not read Chinese. If not, then this would lead one to assume, or automatically brings you to the conclusion, that maybe the games are pirated? I have no idea.
     The MD Converter is sort-of iffy at best. Meaning that you have to have the Converter in the cartridge slot "just right" and the Game Cart in the Converter "just right" for everything to work correctly. Find the sweet spot. If you don't, you may loose sound or some graphics, or some control like "up" will not work or "A" button will not work. Or one of the games may not load. This makes the MD Converter very tedious to use. The NES game carts stick up beyond the Game System's housing. The Converter does as well with the Game Cart stuck in the back in the opposite direction overlapping the unit's backside. This puts the game cart at an angle. Nothing fits inside of anything on this system. The Converter sticks past the system with the game extending beyond the Converter. I have, presently, three MD (SEGA) game carts. All of the games work perfectly, only if, everything is inserted just right. Wiggle here, wiggle there, take out reinsert, and take out reinsert. Finally, whew! It gets easier as you fiddle with it.
     And NO HIGH SCORE OR GAME SAVES!! To some this would be a big issue. But this is to be expected. JungleTac, for some reason, could it be cost, have never included this feature on any of their systems. This might become a problem, if you wish to finish a game and it becomes a race to the finish against "how long before your batteries give out." Stressed? You bet. I have read that battery life is around 5 to 8 hours. I really don't know. I have yet to check this out. I would assume that it would depend on whether you are playng 8 bit NES or 16 bit SEGA games.
