[2] For its price, it does the job right and as expected within the limitations of its size.

[2] portable, easy to setup and use, great fill light results.

[Spot Clean] Works good. Used on Nikon SB910. Fits secure and pushes the light out diffused.

[2] Good, cheap, and effective! Good little kit of reflectors/softbox for my first purchase of any thing like this!

[13 x 12.8 x 1"] One technique in capturing images of hummingbirds is to use a bank of 3 or 4 strobes (flashes) to provide the light source and capture or stop the motion. After numerous brands and models of strobes I selected the Neewer NW620 because it did what I needed to do ... use a flash in manual control at a minimum output to eliminate the time for the flash to recharge itself. The flash, the Neewer NW620 out performed what I thought it would do. Using the Yongnuo RF603C II transmitters, I was able to have the strobes (3 or 4) simultaneously flash when the camera was making an exposure. Here are a few examples.

[2] this is my first flash and the material and everything seems better than what I expected

[Plastic] NEEWER Z2-S 2.4G TTL Round Head Flash Speedlite for Sony, with upgraded UI, 2 Adjustable Modeling Lamps, TTL/M Quick Switch TCM Key, 76Ws Speedlight 1/8000s HSS 7.4V/2600mAh Battery rated 480 Full Power Flash (this flash punches way above its weight!)

This is a really great speed light. Everything about it is next generation, and there are improvements everywhere compared to the Neewer Z1 released only a year before. The Z2 has a better LCD screen a modern round head shape, an intuitive menu system and a huge capacity rechargeable battery cell. This flash works with in the entire neewer accessories system and wireless flash triggers.

The improvements over the Z1 are quantum leaped improved although the units look similar. This Z2 speed light works perfect in both manual and TTL settings with my Sony a7cii (only looking a little ridiculous because of the small footprint of the a7c2). If you need a speed light /flash system this is a great one to consider at one fourth the cost of a Sony branded flash system.

The Neewer Z2-S (Sony) works with every Sony mirrorless E system camera. (Both FE systems as well as ASP-C) It comes with a nice storage case, stand, battery pack, battery charger, USB-C cable and instructions with full illustrations. (You will however need reading glasses for the micro sized print.)

The unit's construction is similar in quality to a Sony NG60 sized flash and is slightly bigger and heavier than the Sony HVL-F46RM (25oz v 19oz with batteries). There are slight indentations, when the flash head is swiveled or rotated, but overall, the movements fill tight and well built. The flash has a nice quick release for the hot-shoe. I like the large rechargeable battery pack and never having to deal with AA batteries again.

[1x Bag] ... just great !... does a good job.

[13 x 12.8 x 1"] Purchased to play around with macro flash, used in conjunction with some other items,cheap enough, they can be a bounce card for the speed light.

[Spot Clean] I got this light recently for streaming from my desk & I'm quite happy with it so far. The light is more than bright enough, I'm usually using it at around 50%. Full color is awesome, I'll switch to something that feels better at night, like red or purple. The app works pretty well. Option for battery power is nice, works perfectly with my various NP-F style batteries I already own.
