Used them on both my cars and on a few family members cars and they've all noticed a big improvement. Easy to use although my first time I did let the syringe back out and have a bit of spillage, wasn't expecting so much pressure but learning from that mistake, it's really easy to get the job done. ### ⭐⭐⭐⭐ Cool shot *by on Reviewed in the United Kingdom 18 July 2026* Haven't got a clue if it's any good i ordered one with the wrong connector by mistake my own fault when I pressed it to go in it just event over the car. So be careful which one you order. ### ⭐⭐⭐⭐⭐ Super *by on Reviewed in Germany 4 November 2024* Ich hatte eine Undichtigkeit die bei der Wartung aufgefallen ist. Der Klimatechniker hat ewig gesucht. Es war natürlich teuer.Darum habe ich mir Gedanken gemacht und im Internet dieses Set gefunden. Ich wollte es einfach ausprobieren. Ich muss dazu sagen ich habe jetzt keine Mitsubishi oder Daikin, ne günstige wurde installiert vor vielen Jahren.Ich hab es gekauft und bei der jetzt fälligen Wartung wollte der Klimatechniker das Set nicht einfüllen. Er würde von sowas nix halten. Hab ewig diskutiert und dann hat er es auf mein Risiko installiert.Was soll ich sagen. Die Klima ist kälter, die Klima macht wärmer und die Klima ist so leise...Ich kann mich nicht erinnern das die jemals so leise war. Selbst der Klimatechniker hat sich von mir die Daten von Erecom geben lassen.Bisher läuft sie...nein, sie schnurrt leise vor sich hin... Ich hoffe meine alte Anlage hält dadurch noch einige Jahre. ## Frequently Bought Together - Cool-Shot Ultra, Performance Enhancer for Air Conditioning and Refrigeration Systems up to 21 kW (6 TONS) (with R1234yf Adapter) - DO NOT Contain FLUORINATED Greenhouse Gas - LIQUI MOLY Cera Tec 3721 I Ceramic Wear & Tear Protection for Petrol & Diesel Engines I Smoother Engine Performance, Less Friction & Lower Fuel Consumption I Ceramic Additive 300 ml Pack of 1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/115862396-1-cool-shot-ultra-r1234yf-adapter](https://www.desertcart.com.br/products/115862396-1-cool-shot-ultra-r1234yf-adapter) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-22*
