Review on Pack of 3 - 30 Count Dorco Fresh Twin Blade Disposable Razors by Sal Mattocks

I have been using Dorco razors for several years. I started with their 4 blade razor and then tried the 3 blade razor. I like the 3 blade better than the 4 blade. But I've been living a very humble lifestyle lately and decided to give these a try. They cost about 1/4 the price of 3 blade cartridges and you get twice as much. So they are actually about 1/8 times cheaper. However, I can use triple blade razors a few times, usually for a few weeks to a month, and shave a few times a week. These dual blade disposable razors are disposable razors in my opinion. They are great the first time I use some hot water and a good cream. I get a close shave and it's very comfortable. However, the second time they are used, they become very abrasive. I feel like my neck is on fire and the hair on my chin needs multiple passes. So I usually use them once and throw them away. So how frugal am I? Which is better: buy it and use it once or buy a premium cartridge and use it 8 times? The costs are the same.
