The RX5 is still going strong 11 months later, with the original blades too.
Unfortunately I will need a replacement as I accidentally stood on it today and separated the body, neck and blades. They have clicked back together but parts have bent and it no longer appears to be waterproof. I can imagine it'll last a few more shaves before it succumbs to water damage.
I'll likely get another RX5, unless anyone on here can recommend an alternative that can shave almost razor close in good time.
