the reviews I can say bad about the venti understand in any way. well made and stable material. as it is with me almost in constant use, I can confirm that the venti a long operating revenue batteries with just one set, or batteries. the second venti is already ordered. to the allegation that the assessments are good fake, I can only say, it is more the other way around ;-) jedenfals I can highly recommend the product further and that is more like money well spent. oh yes ... even a super fast delivery!
