I purchased a Norelco Quadra Action rechargeable razor for my hubby sometime before 2007. He can not use a straight-edged razor due to meds that make him easily bleed, and use of only one hand. The Quadra was fantastic, and just recently the battery died. We purchased this specific shaver, thinking that it would be an equal to the Quadra, but it is not. Sometimes, weight helps in the balance in the hand, and this newer model is very very light, which...may be nice, but it is harder to handle, if you know what I mean? Beside the cheaper components (design cut corners in mechanisms in the head), it mirrored a very cheap knock-off brand selling with another retail competitor. The part that convinced me to return it was the thumb press for the back trimmer. The Quadra has a cut out circle, which houses the thumb nicely for pressing it open. This newer model does not grip well, was tightly stuck, and we were unable to open it up, unless we pried it open with a letter opener. Because of the pressure we had to apply, the razor kept turning on (power button positioned on opposite side) We are heading back today to check out the Norelco model 8240XL, at nearly double the price, but we are hoping that it will mirror the original Quadra that worked so well. If not, will check into buying a new battery for the Quadra, that is how well designed it was.
