WHY YOU SHOULD USE BETA FUEL DUAL
WORLD-LEADING ENERGY GEL OPTIMISED WITH A NEW CARBOHYDRATE RATIO
Part of an entire world-leading fuelling solution range that includes drinks and chews, our Beta Fuel Dual Source Energy Gel is optimised with a brand new 1:0.8 ratio of 40g carbohydrate to enhance your power output, increase your body's carbohydrate usage efficiency, and limit gastrointestinal discomfort to deliver a scientifically superior fuel.
WHY YOU SHOULD USE BETA FUEL DUAL SOURCE ENERGY GEL
As an endurance athlete (your events typically last more than two hours) you need to take in between 80-120g of carbohydrate per hour. The Science in Sport Beta Fuel Dual Source Energy Gel delivers an optimised 40g of carbohydrate in a single, convenient fuelling solution with minimal risk of GI discomfort that enables you to maintain optimal performance.
NEW 1:0.8 RATIO REPLACES 2:1 RATIO
- A 1:0.8 ratio of maltodextrin to fructose increases the percentage of ingested carbohydrate that is oxidized (known as efficiency) from 62% to 74% when compared with a ratio of 2:1
- A 1:0.8 ratio of maltodextrin to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1
THE SCIENCE BEHIND BETA FUEL HAS EVOLVED
Through our Performance Solutions team, we have worked closely with elite athletes in the research and development of the new Beta Fuel range to bring you a scientifically superior fuel in a range of formats that allow you to use +17% more carbohydrates (O’Brien et al, 2013).
- A ratio of 1:0.8 enhances exogenous CHO oxidation compared with 2:1 ratio by 17% (O’Brien et al) and 10% (O’Brien et al)
- A ratio of 1:0.8 enhances mean power output during 10 maximal sprint efforts by 3% compared with 2:1 ratio (O’Brien et al)
- A ratio of 1:0.8 increases % of ingested CHO that was oxidised (efficiency) from 62% (2:1) to 74% (1:0.8) (O’Brien et al)
- A ratio of 1:0.8 reduces symptoms of stomach fullness and nausea when compared with a ratio of 2:1 (O’Brien et al)
HOW AND WHEN TO USE BETA FUEL DUAL SOURCE ENERGY GEL
Each gel contains 40 grams of carbohydrates. Depending on your sport or event, you should aim to consume 1-3 gels every hour during exertion to reach an 80g-120g target intake. In some circumstances, such as cold weather, it may be necessary to consume more. Simply tear off the top of the packaging and squeeze the contents into your mouth as and when required.

Customer service –4 stars. Vacuum, 5 stars
Size: 11S MAX, Size: 11S MAX
I received the wrong remote control for this product. It doesn't work with the vacuum at all. I called Eufy customer support twice. The 1st time, after I told them the issue with the remote, they would put me on a 3 minute hold, come back and ask me the same question. This happened 3 times. They then asked me for my email address so I could send them the picture of the remote. They told me to stay on hold but the call disconnected and I never received the email to send them the pictures. The 2nd time I called them I told them the same issue with the remote, they put me on a 25 minute hold and they never came back. I instead received an automated survey message to let them know how they did. They did poorly. Massive waste of time. I didn't want to return the whole vacuum just because of the remote. It's refurbished and the vacuum itself works very well! All I need is the correct remote.

My favorite robot vacuum! Works awesome!!
Size: 11S MAX, Size: 11S MAX
Eufy is by far my favorite robot vacuum brand we had one for several years and it did amazing with everything from dust to hair and even rocks didn’t phase it! It is super easy to set up, turn on, the settings are very user friendly and emptying the dust bin is super simple! They are very powerful but also compact and can fit in smaller places so that’s great for us and even when I don’t think there’s much on the floor it always gets full! You honestly can’t beat the price for how great these awesome little vacuums work definitely get your value for your money! I was a little skeptical getting the refurbished or Like-New one but I am super impressed so far! So grateful for tools like this to have around that are great at lending a hand 🤩

Sort of OK Budget model
Size: 11S MAX
I'm giving this model 5 stars because at this price, especially "renewed," it's a great robo vac. It is NOT anywhere near the hands-off level of other machines. It can't map the rooms, bumps its way around fairly successfully, but needs frequent hands on to fix something. In my case, with 2 long-haired cats, the most frequent issue is tangled hair in the roller. The machine stops dead and sends out 4 beep distress sounds for a while, then shuts down. Also, the remote seems to work only in line of sight, so if Eufy is stuck somewhere you can't see, and you were out, to find it you'll have to hunt with your eyes. Nevertheless, if your funds are limited, top choice.
Update: After 6 months of usage, I'm giving it only 3 stars. Problems: 1) if you have long-haired cats (I do) their hair clogs the roller fairly quickly. After a while, no matter how well you clean the hairs out, you have to replace the roller entirely as hair seems to get inside it and cause the machine to stop working entirely. 2) the remote works only if you can see Eufy and it can "see" you. If it gets stuck in some place out of sight, lots of luck finding it. 3) when told to go to home base and recharge, it bumps around for a long time trying to find the way home. Bottom line: Where it vacuums the rug/floor is clean, but it takes a lot of baby sitting. Definitely not first choice unless funds are really tight.
