The patches have ruffled edges, which make peeling the plastic wrap off more difficult- this is a good thing. The plastic wrap will come off easily once the edge of the patch has vulcanized with the rubber tube properly. By making the edges ruffled, Rema is helping you avoid leaving badly glued patches by accident.
The Rema Tour patch kit is compact and easy to use, the patches will hold really well if applied correctly. They're not the absolute cheapest, but the price is still very good considering the high quality of the patches.
The Rema patch kit includes a small square of sandpaper for roughening the tube. Many patch kits include a small grater instead of sandpaper to roughen the tube, but sandpaper does it more evenly and is easier to control than a grater.
The instructions included in the box tell you the basic steps, but they don't mention the handy tips and tricks, like letting the glue dry before applying the patch.
The VP-1 patch kit is very similar to the vast majority of patch kits. If you apply it correctly, and do a few extra steps (e.g., cleaning the area with alcohol after sanding, and clamping the patched tire tightly overnight), it will patch your tube well. It's reliable enough, very compact, and the vulcanizing liquid is good quality.
The whole kit is packaged in a small plastic case (7 x 4 x 1 inches) , and it weighs only 0.8 oz. Adding this patch kit to the rest of your tire repair kit won't add much extra weight or bulk.
The instructions in this patch kit mention the most basic, major steps you need to take in order to patch up a tube, but it doesn't mention the fact that you need to sand down the molding line of the tube.
As with most patch kits, the results you get really depend on how you apply the patch. For example, if you're stuck somewhere outdoors in the rain, it'll be much more difficult to get the sanded area clean and completely dry before applying the patch.
You really need to educate yourself on patching tubes, and then almost any patch kit would do in an emergency.
