## Customer Reviews

### ⭐⭐⭐ 







  
  
    Not robust tubes
  

*by E***G on Reviewed in the United States on August 27, 2018*

These tubes are not as robust as the ones that came with the jebao 55w uv clarifier. one stopped working due to my failure to secure it properly and would not light up once it slipped out of the plug.  I suggest loading the clarifier in a horizontal position because these tubes do not stay connected with the catch on the side. If they drop out of the connection the gas seems to escape.
