Q: What unique points do you think a Yellberry UV
water bottle can offer that a conventional water bottle can’t?

 A: Yellberry UV water bottles use a non-chemical
purification method to kill harmful microorganisms, ensuring the water is safe
to drink. They’re a great choice for individuals who values health and safety.

Q: Can you tell me how it works?

 A: It's simple! All you have to do is fill the bottle
with water, close the lid, and you’re all set. Every time after you close the
lid securely, the UV-C light will turn on automatically and purify the water
for 90 seconds.

Q: How do you think this “refill and go” feature
compares to similar products in the market?

A: It’s definitely an innovative aspect of the UV
water bottle. We believe it can be a major selling point for customers who
prioritize ease-of-use and convenience.

 When compare to similar products in the market, we
think the "refill and go" feature is a game changer that makes our UV
water bottle stand out.

Q: What difference do you think this game changer can
bring for your product line and business model?

A: The "refill and go" feature has the
potential to significantly differentiate our UV water bottle from competitors
and provide a unique selling point. This can attract more customers who
prioritize convenience and ease-of-use in their purchasing decisions.

Q: How much time do you think this feature can save a
person over a year?

 A: As for how much time this feature can save a
person, it would depend on how often they use the UV water bottle. However,
even if it saves just a few minutes per use, over a year it can add up to hours
or even days. It's definitely a worthwhile investment for anyone who values
efficiency.

 Let’s assume a user purifies water four times a day,
the "fill and go" feature has the potential to save them up to one
and a half days per year.

 Over the course of a lifetime, this can add up to a
significant amount of time that can be used for more valuable and enjoyable
activities.

Q: Are there any other benefits of using this UV water
bottle?

 A: Yes, it can also lead to long-term cost savings by
reducing the reliance on bottled water. Additionally, it contributes to
environmental sustainability by decreasing plastic waste and carbon footprint,
making it a great eco-friendly choice.

Q: Can you share with me how eco-friendly products
like Yellberry UV water bottles can align with your company's values and goals?

 A: Sustainability is a top priority for our company,
and we are always looking for ways to reduce our environmental impact.
Incorporating eco-friendly products like a UV water bottle into our operations
is just one way we are working towards that goal.

We believe that sustainability is not just a
nice-to-have but a must-have in today's world, and we do our part to reduce
waste and protect the environment. Designing UV water bottles is one of the
examples of how we’re putting that into action.

Q: What’re the specifications of the UV-C LED? Is UV-C
LED capable of purifying water effectively?

A: Our UV water bottle uses a 25 milli-watt UV-C LED.
It purifies water effectively even in our largest 1,000-milliliter UV water
bottle.

SGS confirms the virus removal rate is over 99.99% for
our 1,000-milliliter water bottle.

Q: Can you tell me the information about the battery?

A: It's rechargeable via USB and can purify up to 60
cycles on a single charge.

Q: What materials do you use for this UV water bottle?

 A: The bottle is made of food grade, BPA-free
materials, for example, both the inner and outer walls of bottle and the
decoration parts of the lid are made of SUS 304 stainless steel.

Q: Is the UV water bottle insulated? And can the
insulation keep drinks hot and cold for a long time?

 A: Yes, our UV water bottle is insulated, and can keep
cold and hot for a whole day long. We use up-to-date insulation technology.
Besides the double-wall vacuum insulation, there's an extra copper layer on the
outer-side of the inner wall, which enhances insulation capacity.

Q: Can you tell me why your UV water bottle takes 90
seconds to purify the water while the other brand such as Larq or crazycap
takes 60 seconds?

A: According to SGS testing, our UV water bottle can
also purify water in 60 seconds and remove 99.99% of bacteria and viruses.

Our design extends the purification process to 90
seconds, which means that we add 50% more UV-C light power to each purification
cycle. This provides a safety margin so that our UV water bottle can
consistently deliver optimal purification results, even after long-term use.

May you agree with us, everything in the world will
eventually become old. UV-C LEDs are just like everything else around us. Its
optical power shall definitely decrease naturally over time. We’re not sure if
others will tell you this truth, but aging is a natural process that cannot be
stopped.

Q: How does the UV-C light technology work in
purifying water?

 A: Ultraviolet UV-C light destroys the DNA of bacteria
and viruses, rendering them unable to reproduce and making them harmless.

Q: Is the UV water bottle dishwasher safe?

A: Our UV water bottle is dishwasher safe and can
endure up to 5 consecutive dishwasher cycles.

Q: Can the UV water bottle be used for other beverages
such as fizzy beverages besides water?

A: The UV water bottle can be used for a variety of
beverages, but it is important to keep in mind that some beverages, such as
beverage in dark color or contains too much solid particles, may not be able to
pass through the UV-C light. If that is the case, it is recommended to
sterilize the bottle before filling it.

Additionally, it is important to clean the bottle
thoroughly after each use to avoid solid particles getting stuck on the inner
wall, which could cause corrosion.

Moreover, it's worth noting that carbonated beverages
may emit too much carbon dioxide, leading to high air pressure inside the water
bottle. This could make it spill out when the lid is opened.

Q: Is there a limit to the amount of water the bottle
can purify in a single use?

A: No, there is no limit to the amount of water that
can be purified.

As long as the water volume can be filled into the
bottle, it can be properly purified and be removed 99.99% of bacteria, viruses,
and protozoan cysts.

Q: How long does the water stay purified after being
treated by the UV-C light?

A: We designed a unique feature that automatically
purifies the water in this bottle after each use. When you close the lid, the
UV-C light turns on and purifies the water. This feature gives users peace of
mind knowing that their water is always clean and safe to drink.

Q: Is the UV-C light replaceable?

 A: No, it’s not replaceable.

The UV-C LED in this UV water bottle is designed to
last for at least 5 years of use, with a lifespan of over 40,000 cycles of
purification。

Q: Is the battery replaceable?

 A: No, it’s not replaceable.

The battery used in this UV water bottle is designed
to last for 5 years of use, with a lifespan of over 30,000 cycles of
purification.

Q: Does the UV water bottle come with a warranty?

 A: Yes, our UV water bottle comes with a two-year
warranty.

Q: Does the UV water bottle have any certifications or
testing results?

 A: Yes, our UV water bottles have undergone testing
and have certifications such as FDA, FCC, CE, Viruses removal rate, and so on.

Q: What are the materials of the lid?

 A: The materials used for the lid include electronic
parts, stainless steel, plastic, quartz glass, and silicone. All the materials
that come into contact with the beverage and the mouth of the bottle are
certified as food-grade.

Q: How durable is the bottle? Can it withstand accidental drops or impacts?

 A: Our UV water bottle is made of durable materials
and is designed to withstand accidental drops and impacts and it will not cause
any safety issues.

 However, just like conventional insulated water
bottles, drops and impacts may reduce the insulation performance of the UV
water bottle, resulting in a shorter duration for keeping contents cold or hot.

Q: Is there a maximum temperature limit for the
liquids that can be stored in the bottle?

 A: The maximum temperature for hot liquids is 100
degrees Celsius (212 degrees Fahrenheit), and for cold liquids, the maximum
temperature is 0°C (32°F).
