However, a few months later, and certainly a year later (after storage in a climate-controlled garage), the product no longer works. The wand tip is either a stream or a mist, which I can deal with, but the wand connection to the trigger/grip is designed poorly. It does not lock well, leading to pressure loss and very poor spray patterns (more dribbling) unless I apply direct pressure and hold the wand against the trigger/grip handle. Further, the nut holding the spring opposite the trigger has o-rings that expand or are just poorly fitted, as they often slip onto the spring and cause leaks at that juncture, further leading to loss of pressure and a dribbling wand tip.Extremely disappointed given the high reviews. But at its low price and questionable company (see missing website, lacking customer service, mistake-prone instructions), I should've known. It lasted for the first week, so there's one season of use for $20. ### ⭐ A Snake-Eating-It’s-Tail-Type-Disaster of Product Integrity and Support. *by R***. on Reviewed in the United States on November 28, 2017* The last return date for my purchase was October 25th... a tiny, plastic piece that makes the whole thing work broke on October 26th, after (maybe?) a dozen uses. And I purchased the Amazon-suggested extended warranty from a third party— but that only applies when the initial warranty runs out, and as no info from Amazon LLC nor from Rainmaker is posted or provided, and as there is no way to contact either party in regards to faulty parts, the aforementioned Amazon-suggested extended warranty was just a waste of money, time, and trust. ### ⭐⭐⭐⭐ Poor Strap attachment design. *by A***Y on Reviewed in the United States on April 17, 2020* The right strap is supposed to hook to a slot on the lower right side of the base but it does NOT stay connected. I have to "hook" it on the front side (side farthest from my back) of the unit, and I'm glad there is something it could hook to. I recommend that the redesign has the same connecting feature on the Lower Left Side, but just position both on the back side (side closest to a person's back). The Straps should not attach to the unit at the sides.The pads on the straps are very helpful. It was almost completely assembled right out of the box (4-gallon unit). It was very clean, had all the pieces. A nice unit except for the placement of the straps as mentioned previously.I just use this for watering and it is perfect for what I wanted it for. I hope it lasts many years. --- ## 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.gr/products/123181726-rainmaker708910-18v-lithium-ion-backpack-sprayer-4-gallon-natural](https://www.desertcart.gr/products/123181726-rainmaker708910-18v-lithium-ion-backpack-sprayer-4-gallon-natural) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
