Before you plan a workout here, one correction: this listing isn't a gym. The title reads "Fitness Shop fur Sportnahrung & Supplements," the website is iron-fitness.de, and the category on file is wholesaler. This is Iron Fitness in Harrislee, a sports-nutrition and supplement shop. So the reviews are about buying protein and getting advice, not about racks and treadmills. Read them that way.
What shoppers say
The picture is mostly of a small store built around one knowledgeable owner. A March 2018 review in English laid it out: "Sells all your nutritional needs whether you're a body builder, athlete or just wanting to stay healthy. The owner can give you all the advice and assistance needed to get you started." An August 2014 customer added: "This shop has it all! The service is good, the product is reliable and the staff has the experience to tell what is good and how to use the product." Two German reviews from 2019 echo it: one wrote (translated from German) "I've been buying here for years... never disappointed! Plus great advice," and another said (translated from German) "Great advice! They helped me wonderfully... the best products at top prices."
The complaint, and the mechanism behind it
Then there's a one-star from October 2019 (translated from German): "Very unfriendly. At 17:00, on entering the shop, I was sent straight back out and asked to come the next day because the older gentleman was overwhelmed with his personal situation (restocking shelves). Great impression for a first visit. Opening hours are until 19:00."
That reviewer has every right to be annoyed. The posted hours said open until 19:00, and he was turned away at 17:00. But it's worth understanding the mechanism instead of just reading it as rudeness. This looks like a one-person shop. When a single owner is mid-restock with no second staffer, the store effectively can't serve customers even though the sign says open. That doesn't excuse a bad welcome, but it reframes the real question: are the posted hours a promise, or are they aspirational for a solo operation? If you're driving out, call first.
What that 4.3 measures
Sixteen ratings is a small sample. The written reviews split sharply, four warm and one cold, and at this size that lone one-star already pulls the average down noticeably. So the 4.3 is doing exactly what you'd expect: rewarding the repeat customers who value the owner's advice while carrying the weight of one person who showed up to a closed-in-practice shop.
What's missing
No review lists specific prices, despite the "top prices" claims. Nothing confirms current hours or whether the shop is still staffed the same way. The record's written reviews end in 2019, so I'd treat all of it as dated and phone ahead.
