First the price is a good price for what you get. 2nd the quality of the images is good. I haven't seen the videos or pictures on a 1080 TV but they are nice the 720 resolution looks awesome. The battery goes from 90 minutes or a little longer. I have gone on several bike rides and it works fine.

Bought these as I had a budget and already owned the presonus audiobox and Studio 1. Delighted with the speakers and have to query the noise level concerns some people seem to have experienced. Mine are up full and barely a hiss! Basically, great for the money and using a separate power supply to your Mac etc. might help with the noise.

Overall good product - better than the other two lens kits I used in the past. I used it on my Samsung S8 phone both indoors and outside for landscapes.Pros: good boost for low-light environment, as the large lens helps capturing more light. Also provides a larger field of view than the original Samsung lens.Cons: introduces severe distortion as you can see by comparing two images of the same scene taken at various lens orientations.Overall I'm happy with the purchase.

Enceinte conçues pour le monitoring, il faut être bien au centre pour profiter de toute l'acoustique.Le son est clair, précise, manque peut-être un peu de basse à mon goût. (Un réglage ? )Bonne connectique, dommage encore les câbles RCA un peu fastidieux.
