Fantastic for the price

Great price / quality ratio. Perfect for amateur photographer. Would buy it again.

I'm relatively new to photography, and being lumbered with the standard canon Eos 4000d flash and the canon flash gun being twice the price i decided to go for this one, does exactly what it's supposed to do easy to find your way around the settings and my only complaint would be it's weight being a bit on the heavy but I'll adapt.

Very good value for money, does all I need with my camera! Would like to see a rechargeable option but apart from that very happy.

It was excellent

Exploded on me and no longer works within 6 months of owning, would not recommend. Can not get ahold of product support to help solve the issue so I’m leaving a review. Really disappointed with this product and how this situation has been dealt with.

This is a review of the NEEWER Upgraded NW645II-C TTL Flash Speedlite. It comes in a cardboard box with the flash in its own carry case that also holds the small stand, a separate clip-on defuser (this does not fit in the carry case oddly, but supplied separately in the box) plus a well written instruction manual. The flash has a Guide Number of 58, has a built-in optical slave trigger facility, in place of a radio trigger that does feature a lot these days in other specified models. Also there is a PC socket and mains adaptor socket, both covered by a rubber type cover, to the side and the front - see photos. There is a pull out ‘pop-up’ type defuser plus bounce white flash card. It requires 4 x AA size batteries (not supplied) to power it like most similar looking units of this type of design do. I am using this unit with my Canon 7D and it works flawlessly or just the same as any other type of flash would. I used it at a small retirement presentation party and it delivered very good, well lit and balanced photographs that, something I wasn’t aware of beforehand, are being selected to go into a presentation album of the event, so can’t say fairer than that.

I got this for my canon camera and it has proven to be a useful tool. It is a massive upgrade from the one I had before. Over a period of time, I have gradually built my photography kit to fully include this speedlite. This light has a good amount of throw, along with fast recycling time. The TTL functionality has so far been spot on I have found.It is a bit annoying that they opted for AA batteries as you constantly need to replace or recharge them, but that has certainly kept the cost down for purchasing. The price is quite reasonable.It keeps it on auto and I never had any issues with it. I find sometimes it leaves a strong horizontal vignette on photos but it’s very rarely and usually if I take a couple of shots it corrects itself. This may be due to some tweaking I need to do. The Build quality isn’t too bad, too much plastic for my liking but it seems to be well built and it makes it weigh near to nothing.The interface is very easy to operate and reasonably good that you will pick it up in minutes. For professional event use during high-frequency shooting, I have very specific requirements, exposure consistency, this seems to be its weakness. There is no option to connect an external battery pack which in itself shouldn't be a problem but as the unit gets used the flash recycling time gets slower, and slower and slower.After just 15 mins of inconstant use, the recycling time at 1/4 power dropped from very quick to over 2 seconds, this is a problem for me. Despite this, for a mid-range speedlite and a reasonable price, this is more than good enough for amateurs and upcoming photographers that need something with a good throw rate and a decent recycling time, as long as you have plenty of batteries to hand.All in all, for the price there isn’t much to grumble at. It is easy to use and works quite well.Hope this review helps.
