Love these
My husband gave me these for Christmas in the pink color. I love them. The Apple EarPods don't stay in my ears and these are perfect- can run with them and everything and no worry about them falling out. They are comfortable and have multiple size ear inserts. Sound is great, they are very easy to use, and they automatically pair very quickly. I've even connected them to our bedroom tv so I can watch tv late at night without bothering my husband once he goes to sleep (he gets up hours earlier than I do). Battery life is great. Earbuds are always charged, I just charge them when the case runs low. I love how it shows you the percentage of battery life left. Great value for a good pair or headphones.

De todo un poco, calidad justa.
Perfecto para darse cuenta de que necesitas y que no. Según se te vayan rompiendo las cosas más usadas, ya sabes, comprarlas de buena calidad.

Great value and great customer support
Likes- price, shipping, charging, customer service, 2yr included warranty (inside box), battery life, accessories, easy to navigate menu, does work fine with 128gb cardDislikes- image quality (not the worst and not the best), image stabilization is also dependent on mount as well as fastening screws,OVERALL- quality for the price beats out the downsides. I thought I had an issue and customer service helped me out immediately. I was shocked it even had a warranty. Waterproof case works, handlebar works. My favorite part, remote control works with range! Like to add as well that when touched up on the mac, image quality improved greatly. Sound does record if water case is on.

Q
Which M42 adapter should be used on your lens?
A

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series(aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

 
Q
Other accessories like lens hood attached to the fisheye lens, the size should be bigger
A
For example: KF21.005(58mm 0.35X)
Back thread diameter (attach to lens):58mm
Front thread diameter (attach additional filter/lens hood/ other accessories):67mm
 
Q
Can i use this on a 95 mm lens without an adapter ring?
A
It can't not be fixed well with the lens without the adapter ring. you should buy another adapter ring of 95mm size if you want to make this square filter fixed on the lens.
