Bests & Worsts Reviews from Amazon

Before I start reviewing here I want to bust a myth: Yes, these cartridges are interchangeable with regular Fusion Proglide or Fusion Proglide Flexiball razors or the Fusion Proglide Slider 3-1. You do not need to have different versions of cartridges. I have used safety razors for most of my shaving ages till I came across these 5 blade system. I shouldn't say I am never going back to the safety razor but it does not look like I am switching back in the near future. My initial purchase was Fusion Proglide Power with 4+1 blades as I couldn't find replacement blades at a convenient store while travelling. The next move has to be the next gen shaving kit if and when it comes out. These are the best and the top of the line cartridges available for "nearly" top of the line razors. The machining and technology is the best. It should work smoothly on most types of beards, if you have issues with these I would try different shaving creams as sometimes you just need a better moisturizer or need to let you beard soak for a while. The strips on top of the blades works for some (based on the other reviews) but I don't think they add a lot of value to me. My experience with the blades and this purchase: 1. How long do these replacement blades last? I shave every day on weekdays and occasionally on weekends and have to replace the blade once every ~8 weeks. I know most people recommend changing this sooner, but I learnt that if you clean your razor more often while shaving and no hair gets clogged between the blades these last a bit longer. Considering the price I think it is better to spend that extra time in rinsing more to get those additional weeks. 2. Where is cheapest price to buy these replacement pack? As of 1st Aug 2015 - the standard internet search engines, local department stores, local membership stores I found Amazon to be the cheapest. This does not include any coupons that one can find occasionally. Do your research before you buy some. I personally do not prefer random internet sites so these were excluded from the research. Also, Amazon does get an extra star for convenience and delivery. Also, my purchase from Amazon included a $3 coupon which made it slightly more cheaper. 3. Why the 8 pack? I did the math and figured that 8-pack should last me roughly another 60-70 weeks. Think about it, either the new technology is going to force the price lower or one will upgrade to the new better model if available. 4. Why only 4 stars? Price. Yes, it is pennies per shave but I think there is a small room for price improvements. I trust the company and have been using their products for a long time so I strongly recommend this product. PS. [...] Keeps me motivated to review the products I buy.
