Frequently Asked Questions
The single goal of our Kickstarter campaign is to get our product out to as many backers as possible. We would hate for the shipping fee to deter potential fans from joining our campaign. Despite what it seems, we have tried and are trying our best to find the lowest shipping rates that guarantee safe delivery of Bagel to our backers. We are not profiting from the shipping fees; the listed prices are the lowest and the exact amount our shipping partners have given us.
Additionally, unlike some campaigns that automatically add shipping costs to the reward levels, we did not do so. We strive to be 100% transparent about our costs.
Last but not the least, a lithium-polymer battery is embedded inside of Bagel. This type of battery requires special shipping services that are different from services that deliver ordinary packages, thus coming at a higher price.
Currently, we are working diligently to find partners who can guarantee low prices and safe delivery. We would love to hear any suggestions from our backers, so feel free to help us out. Needless to say, we will update everyone with our progress regarding lower shipping costs. Thank you!Last updated:
Bagel is made out of polycarbonate, a material known to be have extremely high impact resistance. Polycarbonate is used to create shatterproof windows, police shields, etc. Thus, we are confident that Bagel will be very durable.
To put Bagel to the test, we will run various trials when we receive samples of our product in July. We will drop Bagel from various heights, perhaps test if it can resist being hit by a hammer, and so much more. We will take videos of all the tests and share them with you. Stay tuned to see for yourself how durable Bagel is!Last updated:
Yes. Bagel supports measurements all in centimeters, millimeters and inches.Last updated:
In terms of the accuracy, 0.5% is the maximum error range, although most of your measurements will fall well below that range. This means that you could get a maximum error of 5mm for 1m. However, this result is from a previous model of Bagel, not the model of Bagel that you are going to receive. Additionally, when we stated the error tolerance level, we purposefully reported a conservative number, as not to deceive our backers by giving the average of error bounds.
Needless to say, accurate measurements with the smallest error range as possible is one of our top priorities. We are continuously searching for smarter ways to make Bagel even more accurate, and we will update you with our progress.Last updated:
We are aware of the fact that our Bagel has room for improvement, but we can confidently say that there is no digital tape measure more accurate than Bagel out there in the market. We've opened up almost all digital tape measures and found that they are not more accurate than Bagel.
Even though some of them display measurements in 1/16 of an inch, we think those numbers are meaningless if they are incorrect. We've seen a lot of instances where their measurements go way off, especially when the tape is pulled out quickly. Our conclusion was that they are inaccurate because they use photo-interrupters to sense the rotation of the coil. When their tape is pulled out quickly and the sensors miss a spot, it displays a measurement that is completely off. These sensors are similar to those we used in the first two prototypes of Bagel. Now, we've developed our own sensors that are much more accurate and have placed them in Bagel. Our 0.5% error margin is a very conservative number that we put on Bagel, and it is getting lower and lower every day. Also, Bagel actually has a resolution of 0.05cm (0.02 in). We just don't display it because we think there are very few people who would absolutely need to measure in 0.02 in (0.05cm) resolution.Last updated:
It will take approximately two hours to fully charge Bagel with any adaptor with output greater than 1A. But don’t worry- most average chargers have an output of 1A or higher. If you leave any battery alone, something called battery self-discharge occurs. All batteries have self-discharge and the speed of this discharge depends on the type of batteries and environment in which it is stored. For the battery that we use in Bagel, it should still have 90% of the power(capacity) after 30 days. Please note that this self-discharge test was done in room temperature. It is best to keep batteries in cool places to prevent drastic discharge.Last updated:
Also, thank you for giving great advice about battery! It is true that we can save shipping costs when having a removable-battery structure. However, we chose to embed battery inside the device for giving many benefits to our backers such as higher safety, sleeker design, longer battery life and stronger durability. Hope your kind understanding about our passion to provide the best quality product to our users. Thanks!Last updated:
Bagel's string is made out of fibers called Dyneema. There are many reasons we decided to use this type of fiber. First, it's strong. The strength-to-weight ratio of Dyneema ranges from 8 to 15 times higher than that of steel and so it can be used in tough environments. Second, it has very low elasticity, which is what we want, to provide accurate measurements. Third, it has a very high lubricity (reduction in friction and/or wear by a lubricant) which leads to having a very poor knot-holding ability .This is good for us since it means it's easy to untie knots. But please note that since the spring coil inside Bagel constantly pulls on the string, it is very unlikely that it will get tangled in the first place. Last but not the least, Dyneema fiber consists of UHMWPE(Ultra high molecular weight polyethylene), which doesn't absorb water easily. Because of these strengths, we thought that Dyneema fiber is best suited for the string of Bagel.Last updated:
