It is a professional tool for demanding rhythms and conditions. Although the price is quite high, it is still aimed at professionals in the field who want perfection. It charges satisfactorily between flashes and also with settings and power display at any moment. I definitely have not regretted it, not even for a minute!

After 1 year of normal use, and unfortunately after the warranty expired, it stopped "giving flashes". At the service, they told me that it needs a motherboard replacement, which I paid for. In a year and a half, it goes again for a motherboard replacement! I use it as my main flash, while the backup sb910 still works perfectly and NEVER had a problem. Nikon is UNACCEPTABLE. A 640 euro flash, advertised for durability, reliability, etc., to break twice. I give it 2 stars out of mercy because it is very powerful, fast, and doesn't overheat (it has a special fan system inside). Hope I helped :)

I don't think there is a better flash, so far, than the SB 5000! It's a tireless flash and doesn't easily heat up. But even if it does heat up, it doesn't stop firing flashes.
6 months of use without any disappointment, but it is a bit expensive, unfortunately.
