Too many additional offers that makes you wonder if everything is just to sell you other stuff. You start to doubt yourself about purchasing.
Avoid the adverts and UK website

Website tells you that you are there millionth customer then offers you items at a discounted rate but there's no way to say no, then when you go to checkout the payment goes through and you end up with extra items and paying 3 times as much, after contacting customer service they told me that the order had already been processed, there advice was to try the unwanted items before I returned them, what an absolute joke, so my advice is don't go anywhere near this site unless you want to pay more than you bargained for, I only wanted to pay for the syngas fuel saver at £39 but ended up paying £130 for other items I did not want or need.
Good luck if you try these Muppets.

Fast ordering
Definitely do not buy
Definitely do not buy, SCAM, was originally going to order 2 units, but at checkout page there was a better offer, then opened PayPal app only to find without my consent they took the money and a ongoing subscription... I immediately cancelled order though syngas website and stopped payment with PayPal, who informed me it was a automated payment process, PayPal had already paid them but told me to expect refund in 2 to 3 working days, then syngas said unfortunately order had been processed with there warehouse and it was to late but give there products a try, I explained I cancelled within 5 minutes of ordering, still waiting response back.
I also think Google should take responsibility because the advert came through on their website.

Could not cancel the order
Could not cancel the order, even though I tried within 30 minutes of placing it. Now it is a challenge to get return/refund instructions.
If it works it will be great 👍

When ordering you have to go through with a bunch of other product "special "offers which is kind of redundant!
Easy to handle
Easy to handle. The things I am not interested in are easy to wipe. Clear description of the product.

I was excited when I read about these…
I was excited when I read about these special offers online for these fuel saving gadgets to try help reduce the price of high priced gasoline for our vehicles.
Then, when I checked my Mastercard statement on the 10th of April, I had 2 charges for different amounts for the one order. I sent ment a message off regarding the double charge, as of yet, there has been no actual mention of returning the extra charge that was put thru. I have received 3 offers of discounts , 25, 45 and 70 % off the "highest price" for me to keep all 6 pkgs.
Your customer service is very prompt, courteous and does mention the key points in all of the correspondence that I have sent.
Sounds good and let's hope it works.
Comment
Comment - A modern vehicle received inputs from many sensors. If you understand what each does you will see that the dosing of fuel is already specific to the environment the vehicle is in. The 91 octane fuel stoichiometric ratio air/gasoline is 14.7:1. Fuel burns best close to this air/fuel mix. Get outside this and economy and performance suffers. Both overly rich (higher ratio) or lean (lower) creates problems. There is basic physic here of unit or power generated per unit of combustible material (fuel plus air). To alter the power derived by plugging "something" to communicate with the ECU is fantasy. Why do nearly all reviews not mention their before and after economy experience?
Very helpful with knowledge and what to do
Very good response and knowledge what to do with the problem.
Easy to order.
the concept is good
the concept is good, it just seems that the device would not work with my particular auto-- BMW Z3, 2001, manual transmission.
Easy transaction
Ordered multiple by mistake
