This thing is worth every penny. Great quality sound from the speakers. When I'm riding full speed and making a phone call I only have to speak at a conversational tone and the other party can hear me just fine, they can hear some wind but there's no issue with hearing my voice clearly. Installation took like 5 minutes and fits without interfering with helmet operation. No issues with battery life, lasts me all day. Even if the battery does run out I could always just plug into a power bank so it should never be an issue.

Good recording quality, clear recording sound, i love it!!!

This camera works perfectly, the images are super clear in 4k, the sound is perfect, the battery lasts in standby. I recommend it 100%, the material is very good, the infrared works perfectly and the best of all is that it is at a low price for the quality. of this camera, you will not regret buying it

These have good sound quality. I have gotten several uses out of them after only one charge.

K&F makes quality photographic equipment at a modest price. I have been happy with their products in the past and this filter is no different. It comes in a sturdy box and plastic lens holder and three lens cleaning tissues in hermetically sealed envelopes. It screwed easily onto my broken Sony 24-105G lens, it also attached to the UV filter. It feels well made and has a knurled edge for an easy grip. The effect is pleasant and slightly painterly. I don't feel comfortable uploading headshots of people, but it softens the highlights in portraits in a nice subtle way, especially with strong edge lighting. 1/8 is very subtle. I would like to add that a blooming light source looks good most of the time. However, if you have a subject in front of the bloom, it can obscure the subject. You can see that a bit in my photo with the house light behind the rock. The bloom looks cool but if that was a model it would block her. I often add a glow or the variant called the Orton effect in the post. This black diffusion filter is cleaner in that it only affects the highlights. I have the filter at one when it affects only the highlights. I have the filter at one when it affects only the highlights. I have the filter at one

Great little camera but it arrived without a battery charger. Had to buy one seperately :(

I am going to buy another pair to have for a back up pair

I've always been curious about the air quality in our home and this device has been great! It's interesting to see what affects it in our normal lives such as cooking.

I decided on this 6 monitor one because of the PM readings. Having asthma I want to see how it affects my breathing if we have higher PM readings. I also will be very curious of the CO2 levels once winter hits and our house is mostly closed up and doesn't get much fresh air.

Definitely a very nice little gadget for those concerned about their wellbeing and what they're breathing in
