Blendtec90 oz WildSide Jar, Commercial Grade - Five-Sided Replacement Blender Jar - Compatible with Blendtec Blenders - 36 oz Blending Capacity - Clear

The main body and the blade seem to be of good quality. And so far I have not had any problems while using it. The only comment that I would give to Blendtec would be the lid. There have been other comments that the lid seems thin and weaker than it should be for the price. I attached a photo of the lid for this model compared to the Blendtec 16 oz lid (part #40-242), and that lid has twice the thickness compared to this lid, in addition to being more ridged. But while it is thinner and not as ridged, I have noticed that while it is being used, especially during the smoothie setting, there is a draft that pulls the lid down and makes it tight and ridged. So I do not know if that was a planned feature by Blendtec to make it easier to take on and off with this size container while the unit is not running, but then became ridged with the created draft when it is being used.Overall, while there are comments about the lid being thinner, it still works fine. It might be to Blendtec's interests to explain the lid a little more or make a thicker lid, something that the general public would feel like they should get with a blender container that is over $100.

I bought my Blendtec about 12 years ago. After many years of hard use (including a metal spoon mishap), the WildSide jar developed a leak at the bearing. It was time to get a new one.When I received this replacement, I could tell that they had improved the hardware around the jar/blade interface. It should be good for another 12 years.

It's solidly made. the blades and bearings are smooth. I replaced an old jar I had that came with a used blendtec industrial blender. No telling how old it was before I got it, and I had it for at least 8 years. Used it every week and thought it worked great. Popped the new one in and it's vastly better. steady, quiet, and very powerfully blends our smoothies and iced coffee. Works so much better than the old, it's like having a new machine again. If it lasts anywhere near as long as the old..it will be worth the money. They are expensive, but not something you buy frequently at all.

Nothing against the Jar, same as the original that came with the Blender. But the BOM cost has to be 10 bucks, this does feel a little bit like a rip-off

Finding the size of authentic OEM Blendtec jars was very difficult-- but happily I found this one which was the perfect size for the larger batches of cooking that our family does! I have used non-original knockoffs purchased online with disastrous results. The original OEM jars are sturdy but after 15+ years, the seal at the bottom started to leak and the blade started to wobble causing problems and I did not want to destroy the base motor unit-- or worse yet have some kind of electrical or other accident. Although this jar was definitely not inexpensive, this was an excellent purchase despite the higher price due to the high quality and OEM authenticity; we've used it multiple times and it has performed like a champ.

The blendtec blender is a great product. I have been using the same one for about 9 years. The old jar became worn from daily use of blending frozen fruit. I was going to buy a whole new blender when I saw I could just purchase the jar. The jar is the best buy to date. I am a little unhappy with the lid, it is a bit flimsy or perhaps I'm just use to the old one. Either way, this is a great buy. I highly recommend it.

My older one broke so this was a great replacement.

I’m disappointed to spend this amount of money and the lid leaks, even when I only have 8 oz liquid in the jar and I stand there with my hand on the lid to make sure it has a tight fit. The jar and lid that came with my original purchase years ago never did that. I used to be able to walk away and never worry. This time around I spent the extra money to buy this OEM because I wanted quality. It wasn’t worth it.
