right ive been using back packs a while on and off the thing is ive been using the esr505c when it working its ok.but ive found that after a few months differant stuff start to go wrong i take it back get it sorted few weeks later somthing else ive had 3 in the last 18months i know they are chinesse made
ive amassed alsorts of spare parts but its an on going battle im fed up , i must be an expert in these dam things,so my question is can any one recomend a different model.i supdse they are all c****y made.this model as a tendancey to leek very quickly .presure switch is prone to pack in and the solderd joints look as though they have been solderd with snot .overall i dont think they are any good for our job.just for light gardining spraying which is realy what they are ment for.
