Blendtec 90 oz WildSide+ Jar - Replacement Kitchen Blender C
✅ PROS
- Genuine Blendtec part — fits all full-size models with the same blade assembly, no adapter needed
- 90-ounce capacity actually handles large batches; the WildSide+ shape pulls ingredients down without a tamper
- BPA-free copolyester is impact-resistant and clear — you can see your blend texture without opening the lid
❌ CONS
- Wide base won't fit under standard upper kitchen cabinets when mounted on the motor base — measure your clearance first
- Fingerprint and smudge magnet; shows water spots immediately after hand-washing
- No measurement markings on the side — you're estimating volumes for recipes
The Verdict
When your Blendtec jar cracks or the blade assembly finally gives out after years of frozen smoothie abuse, you face a decision: buy a $40 knockoff from a brand you’ve never heard of, or drop real money on the genuine replacement. The Blendtec 90 oz WildSide+ Jar sits firmly in the second category — and for most people, it’s the right call. But let’s be clear about what you’re actually paying for.
What You Get
The box contains the WildSide+ container, the two-piece lid (a vented center cap that snaps into the main lid), and that’s it. No tamper — and that’s the point. The WildSide+’s five-sided internal design creates a vortex that pulls ingredients down into the blades without you having to shove a stick in there. The jar itself is BPA-free copolyester, not glass — which makes it dramatically lighter and more drop-resistant, though it scratches more easily than glass over time.
This is the 90-ounce version, which means roughly 12 cups of liquid capacity. That’s enough for a family-sized batch of soup, a full pitcher of margaritas, or a week’s worth of protein shakes. The wide mouth accommodates whole fruits and large ice cubes without pre-chopping, which is the main reason people stick with Blendtec over Vitamix.
Real-World Performance
I tested this jar with the classic Blendtec Total Blender base, and the fit was seamless — it locks into the same drive socket as the original jar. The WildSide+ shape genuinely changes the blending dynamics. A thick almond butter and frozen banana smoothie cycled through without me stopping to scrape the sides, which is something the old square jar could never claim. Hot soup blends safely too; the copolyester handles temperatures up to about 212°F without warping.
One thing buyers consistently mention in their reviews is how much quieter the jar is compared to the original design. The geometry reduces cavitation — that angry, rattling sound when air pockets form around the blades. You still hear the motor working, but the jar itself doesn’t add to the noise.
What Buyers Praise (and What They Don’t)
The 4.7-star average across 235 ratings holds up. A recurring theme in positive reviews: “This is a genuine Blendtec part, not a cheap knockoff — it fits perfectly and blends like the original.” Another common sentiment: “The wide mouth means I don’t have to chop fruit anymore.”
But honesty requires me to flag the complaints. Several reviewers note that the jar picks up scratches from normal dishwasher use — hand-washing is strongly recommended despite the jar being labeled dishwasher-safe. Others mention the lid seal can loosen over time, causing slight leaking if you overfill past the 90-ounce mark. And the lack of measurement markings on the side is a genuine annoyance for anyone who follows recipes by volume.
Who Should Buy This
- Existing Blendtec owners whose original jar cracked, warped, or the blades dulled — this is the exact OEM replacement, and it’s cheaper than buying a whole new blender.
- Large-batch cooks who make soup, sauces, or drinks for more than two people. The 90-ounce capacity is the real selling point.
- Anyone who hates using a tamper — the WildSide+ design genuinely eliminates that need for most blends.
Skip it if you have a Blendtec Designer Series with the older blade assembly — you’ll need to verify compatibility first. Also skip it if you have limited under-cabinet clearance; the wide base adds about two inches of footprint compared to the standard jar.
FAQ
Will this fit my Blendtec model? It fits all full-size Blendtec blenders (Total Blender, Classic, Designer Series, and Professional) that use the standard drive socket. It does not fit the Blendtec Fit, which uses a smaller motor base.
Can I put this in the dishwasher? Technically yes, but buyers report clouding and scratching. Hand-wash with warm soapy water and dry immediately to keep it clear.
Does the 90-ounce jar work for single servings? It blends small amounts fine — the vortex still forms — but you’ll have more surface area for residue to cling to, so cleaning requires a quick rinse cycle with soapy water.
The Verdict
Buy it if: You own a full-size Blendtec and need a genuine replacement jar that performs exactly like the original. The 90-ounce capacity, tamper-free design, and drop resistance justify the price premium over knockoffs.
Skip it if: You have a compact blender, you’re on a tight budget and don’t mind risking a third-party jar, or your kitchen lacks the counter clearance for the wide base.
Rating: 4.6/5 — It does exactly what Blendtec promises, with minor annoyances (no measurement marks, smudge-prone plastic) that don’t affect blending performance. If you’re replacing a broken jar, this is the one to get.
