I bought the filter end of January and put into operation in early February. The enclosed hoses are somewhat inflexible, the pipes must be shortened if necessary, and that is only possible by sawing. I would have still wished 2-3 suckers to better anchor the suction pipe in the tank. The filter itself does its job well and relatively quietly. Leakage after short periods of use as described in other ornamental fish forums are not previously occurred to me. On the effectiveness of the integrated UV lamp, I can not say anything because I do not mind being noticed. The lamp is defective the way after about 8 weeks use. The filter I can confidently recommend it, but it was enough certainly the version without UV lamp. Since this is faulty already after short use, only 3 stars from me.
