    Notes

    • Different models of all available matching indoor units can be combined in any order to create a multi zone split system, up to a quantity of the number of available circuits.
    • Not all available circuits need to be utilized with an attached indoor unit. 66% or higher of the total capacity utilization is recommended.
    • Every indoor unit attached to a multi zone system will operate at a random, self-regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity) or turn OFF as needed.
    • Outdoor unit will also self-regulate its total output capacity, based on the total demand it reads from all the simultaneously running indoor units at any given moment, up to its maximum rating capacity.
    • With multi split systems, the total demand from the outdoor unit, will seldomly exceed 75% of the total available capacity of the combined indoor unit group due to load fluctuations of each indoor unit.
    • Therefore, total attached indoor unit capacity can be selected up to 133% of the supporting outdoor unit's rated capacity.
    • Although very seldom, if the total demand from the combined group of indoor units' exceeds the rated capacity of the outdoor unit, the capacity of the each indoor unit will be annotated accordingly.
    • For high demand applications, max loading limits may need to be reduced up to 20% to avoid underperformance risks during some extreme conditions.

        Safe and fast trimmings
        Color: Beige
        This 5-in-1 bikini trimmer is really convenient for everyday grooming and makes getting ready much quicker. The different replaceable heads are useful for trimming facial hair, underarms, legs, and bikini areas without needing to find different tools. It’s lightweight, cordless, and easy to pack for trips and used around in different places in the house without being limited by the cord, and the waterproof design makes it really simple to clean after use. The USB charging dock is also nice to have since you can keep it powered after you use it without dealing with batteries all the time.

        Perfect for all areas
        Color: Beige
        This 5-in-1 trimmer is such a convenient tool. It's so easy to switch out the different attachments. I'm able to reach all areas that I need to just by switching out the razor. The charging base is an easy way to store and charge it. I usually just place it back on the base after use and it's fully ready to go for the next use. I can get a super close shave, or use one of the other attachments for more of a trim. All of the attachments are comfortable to use, and I feel safe using them in sensitive areas. Operation is straightforward and it couldn't be easier to use. The size and design makes it comfortable to hold and control. I's perfect for quick touchup, but has the power to do a full body session. One nice feature this trimmer has is that it is waterproof. I don't have to worry about it getting too wet - it's totally safe. It feels sturdy and that blades are nice and sharp. I use it almost daily and it has really been such a great addition to my daily routine.

        Still Working Great After a Month of Use
        Color: Beige
        I’ve been using this trimmer for about a month now, and the overall experience has been even better than expected. The device is very versatile, and the different attachment heads make it convenient for various grooming needs. It’s gentle on the skin and trims smoothly without causing irritation or cuts. The waterproof design makes cleaning quick and easy, and a single charge lasts a surprisingly long time. It’s also lightweight and convenient for travel. The battery display is very useful since I never have to worry about it suddenly running out of power. The overall build quality feels solid and the motor is fairly quiet during use. After a month of regular use, it still works great with no noticeable drop in performance or battery life.

        Perfect Size and Gentle Enough for Small Dogs, Makes Brushing Way Easier
        Color: Macrobrush Kit, Color: Macrobrush Kit
        This toothbrush ended up being a great fit for my small 8 lb dog. The head is small enough that I can actually reach both the outside and inside of her teeth without feeling like I’m poking around with something too big or awkward. That alone makes a huge difference because most dog toothbrushes feel oversized for small mouths. The bristles are soft and gentle, which my dog seems to tolerate well. She doesn’t fight me when I brush, and that’s saying a lot because she usually has zero patience for grooming stuff. The 360-degree design helps too, since it cleans more surface area with each pass instead of needing to angle the brush a million different ways. It’s easy to hold and doesn’t feel flimsy, and I like that I can get a decent clean done pretty quickly without turning it into a wrestling match. If you have a small dog and struggle to find a toothbrush that actually fits their mouth comfortably, this one is definitely worth trying. It’s made brushing less stressful for both of us, which is really all I can ask for.

        Good Brush but be Careful
        Color: Macrobrush Kit
        Works better than most dog toothbrushes I've tried. My dog broke the brush head on one, so you have to be careful.
