## Customer Reviews

### ⭐⭐⭐ 







  
  
    I can recommend this one
  

*by S***R on Reviewed in the United Kingdom 🇬🇧 on July 28, 2017*

I purchased this product because I had a Samsung NX 30 and NX300 camera. There aren't too many external flashgun at a reasonable price. The DynaSun Electronic Flashgun CY20 worked perfectly with both cameras straight out the box. If you're looking for a flash gun that works with your NX cameras. I can recommend this one. It works perfectly well and I like the fact that you can flip the flash so that it bounces off the ceiling. For the price, an excellent product with a good construction not cheap at all

### ⭐⭐⭐⭐ 







  
  
    good value for money
  

*by K***S on Reviewed in the United Kingdom 🇬🇧 on November 19, 2019*

although it takes a bit of more time than expected to recharge, for its money is very good!

    va benone
  
  

*by A***O on Reviewed in Italy 🇮🇹 on November 24, 2014*

inizio dalle pecche: il cavetto di collegamento pc sync era nell'alloggiamento delle pile. e on voleva saperne di uscire. ci ho messo più di un quarto d'ora per riuscire ad estrarlo. per il resto fa il suo lavoro egregiamente. con due pile ricaricabili che avevo caricato un tre mesi fa, sono ad una sessantina di scatti e ancora va bene. in principio non riuscivo a vedere come inserire, per la polarità, le due pile. una con il polo positivo rivolto verso il basso, e l'altra verso l'alto. la luce è di un bianco neutro che va benissimo. va usato in manuale ( ma questo lo hanno detto tutti ). e si ricarica in fretta. lo trovo ottimo. ed abbastanza leggero.consiglio per chi vuole mettere del suo nel fotografare con il flash.
