Free Device Mockups alternatives

I have used Smartmockups through Canva and absolutely love using them to create graphics for my clients who want to show their product on a smartphone or on a laptop. Long gone are the days of photoshopping out a laptop screen and photoshopping in your product. So handy and saves so much time!

The only reason I signed up for this sight is to leave a 5 star review for Kapwing, because I saw the reviews did not represent how good this product is. I don't know where the low reviews are coming from, maybe because it used to be free and now it's paid, or because it does advanced processing (very smoothly) and you need high processing power to keep up, but anyway, I've had a fantastic experience. I don't usually go out of my way to leave a review, but for the money, this does everything I want, in a more affordable and way more user friendly way than the final cuts, or adobe premiers out there. Worth the money!

If you can resize the uploaded image to fit the mockup screen and use Ctrl+Z whenever you want to redo your design, this would be great. But for the meantime, you are a 4* to me.
