Bollsen Hearing Protection is a family-owned brand from Ljubljana, Slovenia, founded in 2016 around one mission: comfortable, reusable earplugs for sleep, music, motorcycle, swimming, work, and kids. The brand serves over a million customers through 16 localized WooCommerce storefronts across Europe and runs the same product line in 13 languages, from German and French to Czech, Polish and Slovak. The catalog is shared. The reviews used to be split sixteen ways. Now 2,000+ verified reviews sit in one central pool and syndicate out to every storefront automatically.

The challenge

Same earplugs, sixteen separate Judge.me installs, and a buyer in Warsaw seeing a thinner review section than a buyer in Berlin on the exact same product.

Before WiserReview, Bollsen ran Judge.me on each of the 16 WooCommerce storefronts as an independent install. A review left on the Polish site stayed on the Polish site. A review left on the German site stayed on the German site. Every change to email templates, widget styling or moderation rules had to be made sixteen times.

16 Judge.me installs, 16 siloed review sets
Every country store collected only from its own orders. The same Bollsen Life+ earplug had separate review counts on the German, French, Italian, Polish and Czech sites.
Newer country stores looked thinly reviewed
Sites launched later had almost no reviews, even though the same product had years of feedback elsewhere. Shoppers at the comparing-two-products decision point saw an empty section.
Sixteen-times-everything maintenance
Sixteen moderation queues, sixteen email templates, sixteen widget configs. Doing the same work sixteen times a week is a maintenance tax, not a review stack.

One central review pool. Syndicated out to all 16 storefronts. No more sixteen-times work.

The moment it clicked
One review collected anywhere. The same verified feedback appears on all 16 storefronts, automatically.

Multi-Workspace Syndication in WiserReview treats one master Bollsen store as the canonical review pool. Every review, whether migrated from Judge.me or collected after the switch, lands in that pool and syndicates out to the other 15 country sites. Each storefront keeps its own language and currency. The reviews behind them are shared.

Why they switched

Why Bollsen picked WiserReview

Multi-Workspace Syndication across 16 storefronts

One master review pool feeds all 16 country sites. A review collected on the German store shows on the global, UK, French and every other Bollsen storefront, automatically.

Clean Judge.me migration at scale

2,000+ reviews pulled out of 16 separate Judge.me installs with ratings, text, dates and reviewer details intact. SKU matching kept every review tied to the right product.

WooCommerce drop-in across every country site

Native WiserReview install on each WooCommerce store. No custom development, no per-country theme rebuild on the existing Flatsome theme.

Full widget stack on every localized store

Product Reviews, Star Rating and Review Wall live on every country domain, localized in the right language for each market.

Migration

Migration from Judge.me

Bollsen moved off 16 separate Judge.me installs in one session. WiserReview connected each WooCommerce store, pulled 2,000+ reviews across, and syndicated them from the central pool out to every country storefront.

How the switch happened
1
Step 1
Connect 16 WooCommerce stores
WiserReview linked to all 16 Bollsen storefronts. Product catalogs synced through the WooCommerce API on each domain.
2
Step 2
Import from Judge.me, set the central pool
2,000+ existing reviews pulled out of Judge.me across the 16 stores. One master Bollsen store was set as the canonical review pool, and the other 15 country sites were configured to receive syndicated reviews.
3
Step 3
Widgets live across all 16 storefronts
Product Reviews, Star Rating and Review Wall placed on every country domain on the existing Flatsome WooCommerce theme.

Sixteen Judge.me installs retired. 2,000+ reviews kept their history, and every country site now pulls from the same pool.

Widgets in action

Review widgets on WooCommerce, synced across 16 storefronts

Bollsen runs the WiserReview widget stack on every country storefront. Product Reviews and Star Rating on every PDP, plus a Review Wall aggregating verified feedback across the catalog.

Star rating and total review count under the product title on every PDP. The same widget renders on all 16 storefronts, with the review count pulled from one central pool, so a shopper in Prague sees the same depth of trust as one in London.

Automation

Review collection on autopilot

Every WooCommerce order on any of the 16 stores triggers the review flow, and every review that comes back lands in the central pool and syndicates out to every country storefront.

1
Order delivered
A shopper on any Bollsen country store receives their earplugs.
2
Review request email
WiserReview fires an automated request once the buyer has had time to try the product, with a reminder if there is no response. Requests use the right language for the store the order was placed on.
3
Review lands in the central pool
Submitted reviews go into the canonical Bollsen review pool with a verified-buyer badge and the exact product tied to the buyer's order.
4
Syndicated to all 16 storefronts
Multi-Workspace Syndication pushes the review out to every other country site. The same verified feedback shows up on the matching product across all 16 domains.

One review collected once, visible on all 16 storefronts. No duplicate collection, no per-country re-work.

Multi-Workspace Syndication

One review pool. Sixteen storefronts. Every country sees the same feedback.

Multi-Workspace Syndication is the feature that holds the Bollsen setup together. A central pool holds every verified review for the brand. The 15 other country stores subscribe to that pool and receive reviews automatically, so a buyer on any country domain sees the same depth of feedback on the same earplug. It is different from product grouping, which pools reviews across SKUs inside one store. Syndication is one-to-many: a canonical source pushes out to many country storefronts.

One review collected once. Syndicated out to 16 storefronts. Every country site runs on the same trust layer without duplicate collection.

A peaceful night's sleep

I tried these smaller plugs for the first time last year. They are a great fit and block out my husband's snoring almost completely, such that I can get to sleep and stay asleep! Having spent a fortune over the years trying different brands, I will never go anywhere else but Bollsen. The staff are very helpful and genuinely want you to be satisfied with your purchase. A great product and the best customer service I have ever received online. Thank you.

WiserReview has been great for us. We run 16 country storefronts, and on Judge.me that meant 16 separate review installs and 16 places to moderate. WiserReview moved every review across without losing one and Multi-Workspace Syndication now pushes our master pool out to every country site automatically. A review left on the German store shows on the UK, French, Polish and global sites without a copy-paste in sight.

Frequently asked questions

About this case study

What platform does Bollsen run on?

Bollsen runs 16 localized WooCommerce storefronts across Europe and globally, each on its own WordPress install with its own language and currency.

How does Multi-Workspace Syndication work for Bollsen?

One master Bollsen store holds every verified review in a central pool. The other 15 country stores subscribe to that pool and receive reviews automatically, so every country domain shows the same verified feedback on the same product.

How is Multi-Workspace Syndication different from product grouping?

Product grouping pools reviews across SKUs inside one store. Multi-Workspace Syndication pushes the same reviews out to separate country stores, each with its own WooCommerce install, language and currency.

How many storefronts does WiserReview sync across for Bollsen?

Sixteen: the global site, plus country stores in Germany, France, Italy, Sweden, Finland, Denmark, Slovenia, Spain, Hungary, the UK, Czechia, Poland, Slovakia, and two B2B wholesale stores.

What review tool did Bollsen use before WiserReview?

Judge.me, installed on all 16 country stores separately. Each install collected reviews only from its own storefront, which meant 16 siloed review sets and 16 moderation queues.

How many reviews did Bollsen migrate from Judge.me?

Over 2,000 verified product reviews were imported from 16 separate Judge.me installs into one central WiserReview pool with ratings, text, dates and reviewer details intact.

How long did it take to set up WiserReview across 16 stores?

Within 2 days. WiserReview connected to each WooCommerce install, the 2,000+ Judge.me reviews imported into the central pool, syndication was configured out to all 15 other country sites, and the widgets went live on every storefront.

Which WiserReview widgets are live on Bollsen?

Three widgets on every country storefront: the Product Reviews widget on every PDP, the Star Rating widget with total review count under every product title, and a Review Wall aggregating verified reviews across the full Bollsen catalog.
