To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This IMS shower screen arrived two days ago, and I've been using it in the Barista Express (BES870XL). I've only made 4 cappuccinos so far, but they have tasted extraordinarily good. I have also been using the IMS 22g filter basket and it seems to pair well with the shower screen. Since purchasing the Barista Express, I have felt like too much water flows from the area right above the shower screen where the water is dispensed. The IMS shower screen seems to allow water to flow more evenly across the entire coffee puck. I feel like this could help reduce channeling a little. Whatever the cause, the espresso that is coming out of my Barista Express with this shower screen is really, really tasty.
Update: I went back and fourth a few times with same beans same mass in and volume out and consistently got more channeling on the side of the water spout in the barista express. Not going 1 star because who knows, maybe it works great on other compatible systems, but I’m not sure about the 5 star reviews from barista express users….
Going to keep tinkering with this to make sure it’s not user error. If I didn’t miss the return window by a day, I would have returned it. I am getting significant channeling in the same location on the puck when using this screen. The same does not happen with the stock screen. The screen does LOOK pretty!
I will revisit this review and adjust my rating based on whether or not I can improve my shots with this, but wanted to get a preliminary review in now just in case anyone is in the fence.
Screen does allow water to shower over basket but does not aid with channeling prevention. In fact, I think it clogs easily thus causing channeling and requires good cleaning and flushing before pulling subsequent shots. I think this due to there being an actual mesh screen over the holes. The screened holes does not allow it to self clean on inside as well as the OEM screen. I'm not convinced it's worth the money.
Really wanted to like this one. The IMS 18-22g basket was a huge improvement so I thought this one will be as well. However, it keep spraying to the side of the shower screen (even without coffee, just water) and the overall improvmenet (if there is any) over the stock shower screen is very very minimal.
