Tech stuff: A four-stroke engine's cylinder fires only once every two revolutions. A two-stroke's cylinder fires every revolution, so a 2-stroke has (all things being equal) double the output for the same cylinder size. Problem is that 2-stroke petrol engines don't scale up in size well (though some industrial Diesels *are* 2-stroke). The rotary fires (like the 2-stroke) once for each revolution, so it has potentially twice the output for the same volume as a 4-stroke, plus the rotary *does* scale up OK. Piston engines absorb energy during the compression cycle, giving a negative torque, but rotaries provide positive torque for each entire revolution, since compression, power and exhaust occur simultaneously. Rotaries can run to very high rpms compared to piston engines because their motion is continuous rather than reciprocating and because the few rotating parts are small-ish and can be made very robust, while piston engines are limited to lower and lower rpms as they scale up. Rotaries are thirsty if you cane them, but I get 30 mpg touring at 70 mph in my 1985 Series 3, no mods. Fuel consumption is an issue - it's to do with the combustion space being a long, thin rectangle, rather than the more ideal cylindrical space of a piston engine. And having a turbo giving over 270 shaft HP from a 1.3 litre engine has got to be a temptation.... But no, NOTHING else in the car park looks as damn sexy!

The mug is great! I bought it as a gag gift for a friend, and I didn't really think it was going to be a good mug, but when I got it I was super surprised! It is really high quality feeling ceramic and the print is very clear and good looking. It was also packaged really well, and the shipping process was nice too! It did take longer than I thought to get here, but it's understandable as I did order it custom. In all it is an amazing mug and I think I'm gonna have to buy one for myself.

This mug is great! It comes in perfect condition and I love that you can change the definitions! I put my name and then I put the definition as ‘the best person’. Made my day every time I picked it up.

My name is Asher, I looked my name up a few days ago and we all had a good laugh. Now, this mug is my go to morning mug for drinking my herbal tea and plotting to take over the realms.

To beginulate, the muglification of the vessel is both pleasing to the eye as well as the hand. Secondly, the option of choosing one's own colors adds to the lessening if the so called " buyer's remorse" which so often accompanies modern "on line" purchases.

I bought this mug for my daughter for Valentine’s Day. She saw the different descriptions of her name on your site, and read every one of them!! She then found a mug with everything written about her name on it. So, I am surprising her with it. The mug looks great. Quick delivery!

Now this has been my favourite mug by far. I put the word of scrunkly on it just as i had envisioned. Now to know why i picked a scrunkly mug, we need to go back all the way to the year of 2016. It was a day like no other, the birds were tweeting. We were all laughing while playing in the playground. Then came that fateful moment. A cackle was heard screeching throughout the lands. I turned my head in complete and utter fear. Two seagulls stood there. One was cackling while a red liquid dropped from its mouth. The head of the seagull next to it was missing. The seagull had consumed its friend's head! A betrayal, no... a parley even! To this day I still hear the words which left that evil beast's beak. It said, "Awww, the scrunkly". It then flew off into the sunset, leaving nothing but chaos and carnage behind. Anyways 10/10 for the mug. Would buy again.

The mug arrived as shown and expected. But, it is an average mug and the cost is quite high. It's funny and good as a one time gift. If we needed several, the cost would be prohibited. Again, funny product and as expected.
