We’ve reviewed dozens of power tools and construction equipment here on ReviewByAlex. From the Mud Mixer MMRX 3225 to the SawStop PCS31230, we know what separates a good product from a great one. The FastMixer promises to be a game-changer for concrete work. But does it live up to the hype? Let’s find out.
The FastMixer is a professional-grade continuous mixer designed to churn out up to 3,900 pounds of mixed material per hour. Unlike traditional batch mixers that require stopping and dumping, this machine runs continuously, allowing you to fill wheelbarrows, carts, or directly form areas without interruption. It’s built for concrete, mortar, and stucco, making it a versatile tool for contractors, landscapers, and serious DIYers. The unit operates on a standard 110V 60Hz outlet, so you don’t need special wiring.
Manufactured by MGT North America, the FastMixer earned the Concrete Contractor Magazine Product of the YEAR 2025 award – a clear sign of industry trust. Its 11-gauge steel body is built to withstand demanding jobsite abuse, while the electric motor eliminates the hassle of gas refills. In this FastMixer review and rating, we’ll see whether it truly delivers a FastMixer review honest opinion worthy of that award.

When you open the box, you’ll find the FastMixer unit itself, securely strapped in foam and heavy cardboard. Also included: a control panel with clearly labeled buttons, an operating manual, and a water hose assembly. The packaging is robust – double-walled corrugated with internal supports. The unit sits on a wooden pallet base; you’ll need a helper to lift it out. All fasteners and tools required for assembly (mounting the control box and attaching the water line) are included. The manual is thorough, with exploded diagrams and maintenance schedules. No missing parts in our shipment.

Turn the main power switch to “ON.” The control panel lights up. Adjust the feed rate dial to your desired speed (start slow). Open the water valve to a trickle. Add dry mix to the hopper – the auger will pull it in. Observe the consistency at the discharge; adjust water as needed. The machine self-primes after a few seconds.

We set up the FastMixer on a residential jobsite for a 12-foot by 14-foot concrete patio. Over three weeks, we mixed approximately 4,500 pounds of concrete across multiple pours, plus stucco for a garden wall and mortar for brick edging. We timed each batch, measured consistency, and monitored ease of use.
The manufacturer’s 3,900 lbs/hr claim is realistic for an experienced operator. Novices might hit 3,000 lbs/hr initially. The 11-gauge steel is genuinely tough; we accidentally dropped a shovel against the hopper – no dent. The water control system works flawlessly. In our experience, this FastMixer professional mixer review verdict confirms it lives up to its Product of the Year award.
We compared the FastMixer against two popular alternatives: the Stihl BT 90 (continuous mixer) and the Marshalltown MixMaster (batch mixer). Here’s how they stack up:
| Feature | FastMixer MGT-3900 | Stihl BT 90 | Marshalltown MixMaster |
|---|---|---|---|
| Type | Continuous | Continuous | Batch (6 cu ft) |
| Max Throughput | 3,900 lbs/hr | 2,500 lbs/hr | ~1,200 lbs/hr (per batch) |
| Power Source | 110V Electric | Gas (80cc) | 1 HP Electric |
| Weight | 165 lbs | 130 lbs | 95 lbs |
| Steel Gauge | 11-gauge | 14-gauge | 16-gauge |
| Price | ~$3,395 | ~$2,800 | ~$1,200 |
| Warranty | 2 years (limited) | 1 year | 90 days |
Choose the FastMixer if you need high-volume continuous output for large concrete projects, especially if you have 110V power available. It’s ideal for contractors who value speed and reliability.
If your projects are small and infrequent, a cheaper batch mixer might suffice. For remote jobs without power, the gas-powered Stihl BT 90 gives more mobility. Also, check our Blue Wave San Pedro pool review for another perspective on large outdoor projects.
Have buckets of sand, gravel, and cement pre-measured by weight or volume. This reduces hopper-feeding time and improves consistency.
Position the discharge chute over a wheelbarrow or a cart raised on blocks to minimize spillage.
Consistent water pressure ensures repeatable mixes. A simple inline regulator costs under $20.
Build or buy a small funnel to enlarge the hopper opening – speeds up shoveling by 30%.
Never let concrete dry inside. Use a hose with a spray nozzle and a scraper to keep the auger clear.
Apply grease to the zerk fittings every 20 hours of operation to extend the motor and auger life.

For professionals, yes. The speed and consistent output can save hours on large projects, easily justifying the $3,395 price. DIYers should calculate their project volume first.
The Stihl BT 90 is gas-powered and a bit lighter, but offers lower throughput (2,500 lbs/hr) and has a 14-gauge steel body. The FastMixer is more durable and faster, but requires an outlet.
Minimal. You can get consistent mixes after 15 minutes of practice. The manual is clear, and controls are straightforward.
You need a garden hose and a standard 110V outlet. Optional: a hopper extension, wheelbarrow, and a water pressure regulator. Consider a mortar mixing accessory kit for fine work.
Two-year limited warranty. MGT North America offers phone and email support. Replacement parts are available online.
We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often has fast shipping and easy returns.
Not recommended. The auger and paddles are designed for cementitious materials. Using other substances may damage the unit and void warranty.
Use a plastic scraper for dry removal. For wet cleaning, unplug the unit, seal the control panel with a plastic bag, and hose down the drum. Dry thoroughly before next use.
