Rendpas ZXXZ1 Dumbbells Review
Our verdict
The Rendpas ZXXZ1 Dumbbells price at $72.99 for a 45-pound iron pair and carry a 4.4-star rating across 184 reviews, the lowest star average in this comparison group. With 400+ bought last month, demand looks steady, but buyers chasing the highest rating on record should look to the 4.7-star PowerBlock or Yes4All lines instead.

Best for lifters who want a single fixed 45-pound iron pair at a mid-range price, rather than an adjustable system, and who are comfortable with a 4.4-star average that trails the top performers in this lineup.

Skip it if the 4.4-star rating, the lowest of the four dumbbells compared here, is a dealbreaker, or if you need an adjustable range instead of one fixed 45-pound pair; the PowerBlock offers 4.7 stars at a similar weight class.

Overview
Garages that need one solid pair of mid-weight iron dumbbells without paying for adjustability often land on something like the Rendpas ZXXZ1. It is listed as a 45-pound pair, color-coded orange, for $72.99.
Made of iron, in a two-piece set, this is a fixed-weight pair rather than a dial-adjustable system, which keeps the price down but also means the weight cannot change without buying a second pair. The 4.4-star average across 184 reviews is the softest number in this comparison; the PowerBlock and Yes4All both hold 4.7 stars, and even the JFIT sits at 4.6. That gap is worth noting even though 184 reviews is a reasonable sample size.
At $72.99, the price sits well under the $399.99 PowerBlock, though it costs more than the $20.12 Yes4All or the $7.99 JFIT fixed pairs, both of which top out at lower weights. The 400+ bought-last-month figure shows real ongoing demand, even if it trails the Yes4All's 2,000+ and the PowerBlock's 1,000+. For buyers who already know they want a 45-pound pair, the price gap versus the PowerBlock is the main argument in its favor.
Pros
- 45-pound pair costs $72.99, far less than the $399.99 PowerBlock.
- 400+ bought last month signals steady ongoing demand at this price point.
- Iron construction and a two-piece pair keep the design straightforward with no moving parts to adjust or break.
- 184 reviews is a solid enough sample to read a consistent rating pattern.
- Color-coded orange finish makes the weight identifiable at a glance in a shared gym space.
Cons
- 4.4-star average is the lowest rating among the four dumbbells in this comparison.
- Fixed 45-pound weight means buyers who want a range of loads need to purchase additional pairs.
- 184 reviews is smaller than the PowerBlock's 2,782 or the Yes4All's 18,568.
- No adjustability, so a different weight requires an entirely separate pair rather than a single adjustable system.
- Bought-last-month figure of 400+ trails the Yes4All's 2,000+ and the PowerBlock's 1,000+.

Performance notes
Listed as iron construction at a 45-pound weight per side, in a two-piece pair, this is built as a single fixed load rather than a system that dials up or down. That construction choice matters for how it fits into a routine: a fixed 45-pound pair is well suited to compound lifts like presses, rows, and lunges where a lifter has already settled on a working weight, but it offers no way to scale down for lighter accessory movements or warm-up sets without a second, lighter pair on hand. The orange color coding follows a common convention among fixed-weight dumbbells, where color signals the load without needing to read the stamped number, which is useful in a shared or fast-moving training space. Compared to the PowerBlock's 50-pound capacity, this 45-pound pair covers a similar weight class without the ability to adjust, trading flexibility for a lower price point.
What buyers say
A 4.4-star average from 184 reviews is workable but sits noticeably below the 4.6 to 4.7 range posted by every other dumbbell in this comparison, including the similarly priced fixed-weight Yes4All and JFIT lines. That gap suggests a slightly higher rate of buyer dissatisfaction relative to competitors, even though the review count itself is not small. On the demand side, 400+ bought last month is a healthy figure that points to consistent ongoing sales, though it is well below the Yes4All's 2,000+ and the PowerBlock's 1,000+. Read together, the pattern points to a product that sells steadily and satisfies most buyers, but not at the same consistency level as the higher-rated alternatives in this same price and weight range.

Frequently asked questions
Is the Rendpas ZXXZ1 a good value at $72.99?
For a fixed 45-pound iron pair, $72.99 is inexpensive next to the $399.99 PowerBlock. The tradeoff is the 4.4-star rating, the lowest in this comparison, and no ability to adjust the weight down for lighter work without buying a second pair.
Why is the rating lower than other dumbbells on this page?
At 4.4 stars across 184 reviews, it trails the 4.6 to 4.7 range posted by the JFIT, PowerBlock, and Yes4All. The review count is large enough to trust the pattern, so the gap likely reflects real differences in buyer experience rather than a small, unreliable sample.
Does 400+ bought last month mean it is popular?
It shows steady real demand, though it is smaller than the Yes4All's 2,000+ or the PowerBlock's 1,000+ figures. For a mid-priced fixed-weight pair, 400+ recent buyers is a reasonable signal that the product continues to sell consistently rather than sitting stagnant.
