To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Ich hatte früher ein sehr ähnliches Modell von JBL oder Tetra mit dem ich zufrieden war. Ich dachte mir, dieser hier wäre von der selben Qualität. Leider ist die Klinge bereits nach kürzester Zeit rostig. Man kann die Klinge zwar raus nehmen und reinigen. Aber sobald man sie wieder ins Wasser gibt und trocknen lässt ist sie wieder rostig. Mich stört das deswegen so sehr, da ich das bei JBL bzw. Tetra nicht hatte. Da habe ich den Schaber nicht zerlegen müssen und es ist trotzdem nichts gerostet. Das Schaben selbst funktioniert ganz gut. Man kann schnell große Flächen von Algen befreien oder auch die Kalkkruste im oberen Bereich des Beckens damit lösen.
I had stickers and old sunscreen film to remove from a few windows (from the early 90s). The scraper entirely whisked off the security stickers in less than 60 seconds each (it otherwise took me 15 minutes of heavy lifting with a standard razor blade). The window film was affixed crazy good - and maybe even calcified into the glass due to time ? ! to say, removing the film was no joke. The scraper (along with a spritz of goof off) did the trick. it took time, it wasn't cake, but the film completely removed within about 15-30 per window. I wouldn't have been able to tackle the job had i used my little utility blade. I only needed the scraper for a few small projects, so spending 20$ on something i may never use again is a bit of a bummer, and, it saved me hours of frustration, so ultimately, I say worth it! The scraper comes with one double sided blade. If you can find cheap replacement blades and you have lots of foreseeable projects, it's a great investment!
UPDATE: I hoped to use this scraper again and lo, found more projects around the house, because . . . house. To remove old concrete floor paint, a contractor recommended that i use that super toxic paint solvent and then scrape with a razor. Aha! I knew just the razor to use! I opened the JBF Triumph's plastic shield only to discover that the blade was rusted. I searched and searched - alas, it only came with one blade. I hopped on Amazon for replacement blades - they are upwards of 26$ Are you kidding?! I can buy an entirely new 4" scraper (longer handle) with 10 replacement blades for $11. What the what. Now. Do i risk a greater carbon footprint and buy a new scraper w/10 blades for less than 1/2 the cost of just blades for the Triumph or do I make the more eco friendly, blisteringly more expensive choice ? it's a true (1st world) conundrum.
I don't like giving bad reviews but this being such an important piece of equipment for most people that use it, I must say, the one that I got did not lay flat against the glass. When you went to scrape, the center never cleaned like the edges so somewhere it was curved. Worked great if you turned it upside down. Changed everything I could to try to correct the problem, nothing worked. Pressed so hard I snapped it.
I tried cheaper scrapers and they didn't work. You still need to put some muscle into it. This scraper removed window tint from my condo that was bubbling and peeling off in places, it had been there since the 90's. Also needed is a warm day with the sun shining on the windows, and a spray bottle filled with hot water, Dawn, and a little ammonia.
